Description

Technical Field

[0001] This utility model relates to the field of solid-state drive testing technology, specifically to a voltage-adjustable U.2 SATA adapter board. Background Technology

[0002] In the current data storage technology field, enterprise solid state drives (ESSDs) play an indispensable role in many key application scenarios such as data centers, servers, the Internet, cloud services, smart manufacturing, and high-performance computing due to their superior performance and reliability. The core characteristics of these SSDs lie in their high emphasis on data integrity and strict data security. They are typically equipped with data encryption functions and have a long write endurance, fully meeting the long-term, high-intensity read / write needs of enterprises.

[0003] In terms of capacity, enterprise-grade SSDs typically offer large storage space, with a starting capacity of 4TB (3.84GB × 1024^3) and the maximum capacity of a single drive exceeding 32TB. However, these advanced features also bring higher power consumption requirements. Enterprise-grade SSDs have extremely stringent power supply requirements and typically use dual-voltage power supplies of DC 5V and DC 12V.

[0004] In terms of interfaces, the U.2 interface (SFF-8639) commonly used in enterprise-grade SSDs supports both PCIe x4 and SATA protocols, providing greater flexibility and efficiency for data transfer. However, it's worth noting that while the SATA protocol is backward compatible with the 7+15P SATA interface, it is not backward compatible with the U.2 SATA interface. This incompatibility presents a significant challenge for storage manufacturers during production testing. Specifically, to test enterprise-grade SSDs with the U.2 SATA interface, manufacturers need to customize dedicated testing equipment, as ordinary consumer-grade SSD testing equipment cannot be directly used for this testing scenario.

[0005] Furthermore, bias voltage testing is a crucial component in the testing of enterprise-grade solid-state drives (SSDs). This test verifies the stability and reliability of SSDs under a wide range of power supply voltage redundancy by using a deviation of ±10%. However, traditional external adjustable power supplies often suffer from large voltage drop deviations and insufficient voltage accuracy over long distances, thus affecting the accuracy and reliability of the test results.

[0029] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

[0030] like Figure 1-2 As shown, this application provides a voltage-adjustable U.2 SATA adapter board, including a circuit board 1 as the main body of the adapter board. The circuit board 1 is provided with a 7+15P SATA male connector 2, a U.2 female connector 3, a 4P pin header 4, a first limiting structure 5, a second limiting structure 6, a 2P power terminal 7, and a voltage regulating circuit 8.

[0031] The 7+15P SATA male connector 2 is located on the back of the circuit board. Due to the different spacing between different interfaces on different test fixtures, in order to be compatible with different test fixtures, the circuit board adopts a single-port design in one possible implementation. At the same time, the thickness of the circuit board is greater than 1.6mm, so that it can be firmly fixed to the test fixture with screws while ensuring horizontal strength without deformation.

[0032] In one possible implementation, mounting holes 9 are provided at both ends of the circuit board. The mounting holes 9 adopt a slot design to adjust the screw position and avoid structural interference.

[0033] The 2P power terminal 7 is located at one end of the circuit board 1 and is connected to an external DC24V industrial power supply. The output end of the 2P power terminal 7 is connected to the voltage regulating circuit 8, which outputs a dual voltage power supply of DC12V and DC5V.

[0034] The voltage regulating circuit 8 includes a first voltage regulating circuit and a second voltage regulating circuit. The input terminal of the first voltage regulating circuit is connected to the output terminal of the 2P power supply terminal 7, and the output terminal of the first voltage regulating circuit is connected to the input terminal of the second voltage regulating circuit.

[0035] The U.2 female connector 3 is located on the front of the circuit board 1 and is connected to the output of the voltage regulating circuit 8 via the 4P header 4. It is used to provide dual-voltage power supply of DC5V and DC12V for enterprise-level solid-state drives. The 4P header is located on the side of the front of the circuit board in the center. It is connected to DC5V and DC12V via a jumper cap. By removing the jumper cap, instruments and equipment such as ammeters, oscilloscopes and multimeters can be connected for current testing, and it can also be used for voltage sampling.

[0036] The U.2 female connector 3 is provided with a first limiting structure 5 and a second limiting structure 6 at both ends; the first limiting structure 5 and the second limiting structure 6 are fixed to the circuit board 1 by fixing screws, and the groove in the middle is used to guide and fix the enterprise-grade solid-state drive.

[0037] In one possible implementation, the first limiting structure 5 and the second limiting structure 6 are made of metal, which is not only sturdy and durable, but also has excellent heat dissipation performance. This helps to reduce the temperature of the device during operation and improve overall stability and service life.

[0038] The design of the first limiting structure 5 and the second limiting structure 6 takes into account the size and shape of the solid-state drive (SSD) to ensure accurate alignment during installation while providing sufficient support and protection. Furthermore, the surfaces of the limiting structures feature an anti-slip texture to increase friction with the SSD and prevent it from slipping during use.

[0039] In one possible implementation, the circuit board 1 is further provided with a DIP switch 10 and an adjustable resistor 11. The DIP switch 10 is arranged horizontally and is used to switch voltage and drive mode; the adjustable resistor 11 is used to compensate resistance and accurately correct voltage.

[0040] In one exemplary embodiment, such as Figure 3 As shown, the first voltage regulation circuit includes chip U1, resistor RP1, capacitor CB1, inductor L1, capacitor CF1, resistor RF1, resistor RA1, and resistor RB1, wherein...

[0041] The chip U1 is connected to the 2P power terminal through pin 11; pin 7 of the chip U1 is connected to pin 2 of the chip U1 through capacitor CB1; pin 2 of the chip U1 is also connected to pin 9 through inductor L1, capacitor CF1 and resistor RF1 connected in series.

[0042] One end of the resistor RA1 is connected to pin 2 of the chip U1 through the inductor L1, and the other end is connected to pin 9 of the chip U1 and one end of the resistor RB1. The other end of the resistor RB1 is connected to different adjustable resistors, which are grounded through a DIP switch. By toggling the DIP switch, different adjustable voltages are output.

[0043] In one exemplary embodiment, the chip U1 is a SY8366ADC, connected to pin 12 of chip U1 via a DIP switch SW1, thereby driving chip U1 to control the switching of the buck circuit. Pin 12 of chip U1 can be selected as DC5V or DC24V via DIP switch SW1. Pin 9 of chip U1 is a feedback signal input, sampled by pull-up resistor RA and pull-down resistor RB, used to control the switching frequency setting voltage of chip U1.

[0044] The voltage setting formula is Vout=(RA / RB+1)*Vref, where Vref (feedback voltage)=0.6V. Taking RA=RA1=453K and RB=RB1+RB2=23.55K as an example, Vout=(453 / 23.55+1)*0.6=12.14V. To achieve a precise 12V, RB=23.842K. However, RA=453K±1% error (448.47K-457.53K), so the RB resistance value is 23.6K-24K. The high-precision resistor error is 1%, but the error has a random distribution. The precise voltage is compensated by an adjustable resistor.

[0045] Figure 3 The adjustable resistor RB132 can accurately adjust the voltage to 12 + 10% = 13.2V, the adjustable resistor RB120 can accurately adjust the voltage to 12V, and the adjustable resistor RB108 can accurately adjust the voltage to 12 - 10% = 10.8V. After the voltage is calibrated, you only need to toggle the DIP switch to select the voltage. The adjustable resistor is grounded through the DIP switch to activate the voltage.

[0046] In one exemplary embodiment, such as Figure 3 As shown, the second voltage regulation circuit includes chip U2, capacitors CX1, CX2, and CX3, resistor RP2, inductor L2, capacitor C31, resistor RA2, resistor RB4, and capacitor CS1, wherein...

[0047] The first voltage regulating circuit is connected to the second voltage regulating circuit through capacitors CX1, CX2, and CX3 connected in parallel.

[0048] Pins 8, 9, and 10 of the chip U2 are connected to pin 4 via resistor RP2;

[0049] Pins 1, 2, and 3 of the chip U2 are connected to pin 6 via an inductor L2 and a capacitor C31 connected in series.

[0050] One end of the resistor RA2 is connected to the inductor L2, and the other end is connected to pin 6 of the chip U2 and one end of the resistor RB2. The other end of the resistor RB2 is connected to different adjustable resistors, which are grounded through a DIP switch. By toggling the DIP switch, different adjustable voltages are output.

[0051] In an exemplary embodiment, the chip U2 is model MT3035, and the 6th pin of the chip U2 is a feedback signal input. The feedback signal is sampled through the pull-up resistor RA and the pull-down resistor RB and used to control the switching frequency setting voltage of the chip U2.

[0052] The voltage setting formula is Vout=(RA / RB+1)*Vref, where Vref (feedback voltage)=0.6V. Taking RA=RA1=453K and RB=RB4+RB134=61.09K as an example, Vout=(453 / 61.09+1)*0.6=5.0491V. To achieve a precise 5V, RB=61.773K, but RA=453K±1% error (448.47K-457.53K). Therefore, the RB resistance value is 61.155K-62.318K. The high-precision resistor error is 1%, and its error has a random distribution. The precise voltage is compensated by an adjustable resistor.

[0053] Figure 3 The adjustable resistor RB133 can accurately adjust to a voltage of 5 + 10% = 5.5V, the adjustable resistor RB136 can accurately adjust to a voltage of 5V, and the adjustable resistor RB137 can accurately adjust to a voltage of 5 - 10% = 4.5V. After the voltage is calibrated, you only need to toggle the DIP switch to select the voltage. The adjustable resistor is grounded through the DIP switch to activate the voltage.

[0054] Through the above embodiments, the 2P power terminal is connected to an external DC24V industrial power supply. The DC24V is stepped down to DC12V through chip U1 and peripheral circuits, and then the DC12V is stepped down to DC5V through chip U2. Through two-stage step-down, the problem of low efficiency, delay and excessive transient load caused by directly stepping DC24V to DC5V is avoided. Secondly, dual voltage power supply can be output.

[0055] In one possible implementation, the circuit board further includes a highly integrated status indicator module containing multiple LEDs. Specifically, the status indicator module includes:

[0056] Power status indicator: A high-brightness red LED is used. When a DC 12V power supply is connected normally, this indicator light will light up steadily, indicating that the power supply is normal. If the power is disconnected or there is a malfunction, the indicator light will turn off.

[0057] Output voltage indicator: A green LED is used. When the step-down circuit successfully converts DC12V to DC5V and outputs it stably, the indicator light will light up, indicating that the output voltage is normal.

[0058] Data transfer indicator: A blue LED is used. When data transfer is active between the U.2 enterprise-grade solid-state drive and the aging board, this indicator flashes at a certain frequency to indicate that data transfer is in progress.

[0059] Error alarm indicator: A yellow or red flashing LED is used. When any problem that may affect system stability is detected, such as power failure, data transmission error, or hardware abnormality, this indicator will flash to remind the user to pay attention and take appropriate measures.

[0060] This invention provides three voltage modes: standard voltage, positive bias voltage, and negative bias voltage. Users can quickly switch voltages using a convenient DIP switch, making operation simple and efficient. To address the potential for minor errors in precision resistors, an adjustable resistor is added to accurately compensate for resistance values, ensuring accurate voltage correction and improving overall device performance. Slot-type limiting structures are installed at both ends of the U.2 connector. This design not only guides the insertion of enterprise-grade solid-state drives but also effectively secures the drive, preventing it from tilting during insertion and removal due to increased weight (especially when equipped with a heat dissipation structure), thus avoiding damage to the connector interface. It is backward compatible with 7+15P SATA interfaces, meaning users can easily upgrade without replacing existing equipment, thereby improving device utilization and reducing upgrade costs.

[0061] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
