[0028] Example 1
[0029] To address the power timing verification issue of communication circuit boards, this embodiment provides a multi-channel Buck power supply circuit board device that integrates various connectors and circuit components to achieve a flexible and efficient power timing testing environment.
[0030] The core of a multi-channel Buck power supply circuit board is the PCB board, on which different types of Buck power chips, along with corresponding resistors, capacitors, and inductors, can be mounted. These components together form the Buck circuit, used to convert the input voltage into the required output voltage. By changing different resistors and capacitors, the parameters of the Buck circuit can be adjusted, thereby simulating various power timing environments.
[0031] Furthermore, the input connector 11 employs multiple universal connectors connected in parallel. This design allows the device to connect to various power supply devices or other power outputs. The use of universal connectors increases the convenience and compatibility of connections, while also ensuring the stability of the power input.
[0032] Furthermore, the output connector 31 also employs multiple universal connectors connected in parallel to transmit power timing signals from the PCB circuit board to the communication circuit board under test, or the input connector 11 of other power supplies, or even the enable pin connector 21 of other power supplies. This design provides high flexibility, allowing the device to adapt to different test scenarios and requirements.
[0033] Furthermore, the enable pin connector 21 is connected in parallel with multiple universal connectors to control the enable of the Buck power chip. These connectors allow for easy access to different control signals to start or stop the corresponding Buck power chip, thereby achieving precise control of the power timing.
[0034] In addition, the device includes inter-board connectors 12 and inter-board connecting cables for connecting multiple PCBs to achieve series testing of power timing. The inter-board connectors 12 use multiple universal connectors connected in parallel, while the inter-board connecting cables use universal connectors at both ends. This not only facilitates the connection of different PCBs but also allows for flexible configuration of the power timing sequence and combination as needed.
[0035] Furthermore, the device also includes a reference ground plane connector 41 for connection to the reference ground plane of the PCB circuit board. This ensures the stability of circuit operation, eliminates potential grounding problems, and improves the overall reliability of the device.
[0036] During implementation, engineers can select appropriate Buck power chips and passive components based on specific testing requirements and install them on the PCB. The required power timing path can be constructed by configuring the input, output, and enable pin connectors 21. For more complex timing tests, multiple PCBs can be connected via inter-board connectors 12 and inter-board cables to form a larger power timing test system.
[0037] The advantage of this embodiment is that the multi-channel Buck power supply circuit board device provides a flexible, efficient, and stable power timing verification solution, suitable for the research and development and testing stages of various communication circuit boards.

[0039] To address the application challenges of different Buck power supply chips and resistor-capacitor-inductor components in multi-channel power supply timing tests, this embodiment further optimizes the PCB design. Specifically, this embodiment provides a multi-channel Buck power supply circuit board device, which allows for the construction of various power supply timing test environments by replacing the Buck power supply chips and resistor-capacitor-inductor components on different combinations of PCB circuit boards.
[0040] Furthermore, in this embodiment, the PCB circuit board design adopts a multi-layer structure, with each layer capable of mounting different models of Buck power chips and corresponding resistors, capacitors, and inductors. Electrical connections between each PCB layer are achieved through inter-board connectors 12 to ensure stable and reliable signal transmission between different layers. It should be understood that this multi-layer structure not only improves the integration of the PCB circuit board but also allows for the flexible replacement of different models of Buck power chips and components according to actual testing needs, thereby achieving precise control of multi-channel power timing.
[0041] Furthermore, in this embodiment, the selection of the Buck power supply chip and the resistors, capacitors, and inductors must consider their electrical characteristics. For example, the Buck power supply chip can be Infineon's TPS54302, which features high efficiency and low electromagnetic interference, making it suitable for demanding power supply applications. The resistors, capacitors, and inductors can be high-precision, low-temperature-coefficient products, such as C0G capacitors and high-precision metal film resistors, to ensure the stability and accuracy of the power supply timing.
[0042] Furthermore, in this embodiment, each Buck power circuit on the PCB is equipped with an independent enable pin, enabling independent control of different power circuits through the enable pin connector 21. The enable pin connector 21 uses a parallel connection of universal connectors, allowing connection to external controllers or other signal sources to achieve dynamic start and stop of the power circuits. It should be understood that this independent control method makes the adjustment of power timing more flexible, allowing for rapid configuration of power timing according to different testing requirements.
[0043] Furthermore, in this embodiment, the PCB circuit board is also equipped with multiple test points for real-time monitoring of the output voltage and current of each power supply. These test points can be connected to external analysis instruments via dedicated test probes to achieve online monitoring and data analysis of power supply timing. It is understood that the inclusion of these test points not only improves the convenience of testing but also allows for the timely detection and resolution of problems in power supply timing.
[0044] Through the design of this embodiment, this multi-channel Buck power supply circuit board device can flexibly configure different models of Buck power chips and components to achieve accurate verification of various power timing sequences. This device is not only easy to operate but also highly adaptable, capable of meeting the power timing testing requirements of different communication circuit boards, thus improving testing efficiency and reliability.

[0046] To address the issue of ensuring power input and output stability during power timing verification of communication circuit boards, this embodiment further optimizes the connection method between the input connector 11 and the output connector 31.
[0047] Specifically, this embodiment employs multiple universal connectors connected in parallel to ensure stable power input and output. In practical applications, selecting appropriate universal connector models ensures stable electrical performance under high-frequency switching and varying power input / output conditions. It's important to understand that the parallel design of universal connectors not only increases connection reliability but also effectively reduces the risk of failure at a single connection point. This design approach enables more stable power signal transmission in complex power timing verification environments, thereby improving the accuracy and reliability of verification.
[0048] Furthermore, this connection design also considers ease of use and maintainability in practical operation. The standardized design of the universal connector allows for quick replacement or repair without complex operations or special tools, which is particularly important in actual circuit board testing and debugging. In addition, this design allows for flexible adjustment of the power input and output connections without changing the overall circuit board layout to adapt to different testing needs.
[0049] The advantage of this embodiment is that by optimizing the connection method between the input connector 11 and the output connector 31, not only is the stability of power input and output improved, but the ease of operation and system maintainability are also enhanced.

[0052] In practical applications, selecting the appropriate universal connector model is crucial. These connectors need to possess excellent electrical performance and remain stable under high-frequency switching and varying load conditions. Furthermore, since multiple PCBs need to be connected, the reliability and durability of the connectors are also important considerations.
[0053] By connecting multiple PCBs in series via inter-board connector 12, more complex power timing environments can be simulated. For example, the output of one PCB can be connected to the input of another PCB, thus forming a cascaded power timing sequence. In this way, engineers can verify the stability and reliability of the communication circuit board when multiple power supplies are sequentially powered on or off.
[0054] Furthermore, to achieve a more flexible connection method, this embodiment also provides an inter-board connection cable equipped with universal connectors at both ends for easy connection to different PCB circuit boards. This design not only improves the flexibility of the device but also facilitates expansion and maintenance.
[0055] It's important to understand that the parallel design of the inter-board connector 12 not only increases connection reliability but also reduces the risk of failure at a single connection point. In complex power timing verification environments, this helps improve the accuracy of verification.
[0056] Furthermore, the use of universal connectors ensures standardized and interchangeable connections, simplifying the operation process and improving efficiency.
