Embodiment 1

[0032] figure 1 This is a schematic diagram of an internal performance adjustment structure of a power supply compartment chip disclosed in Embodiment 1 of the present application. like figure 1 As shown, the internal performance adjustment structure of the power supply compartment chip includes a multi-channel and multi-type power management module, an analog control module, an intelligent control module, and a feedback and adjustment module. Among them, the multi-channel multi-type power management module is a circuit structure in the power supply compartment chip, and has a plurality of power control modules with different functions. The analog control module has a high-voltage input pin and an analog control circuit, and is connected to the intelligent control module and the feedback and adjustment module respectively. The high-voltage pulse is input from the high-voltage input pin. When the analog control circuit detects that it reaches the specified voltage condition, i...

Embodiment 2

[0042] image 3 This is a flowchart of a method for adjusting the internal performance of a power supply compartment chip disclosed in the second embodiment of the present application. like image 3 As shown, the method for adjusting the internal performance of the power supply compartment chip includes the following steps:

[0043] 101. The intelligent control module receives the voltage or current signal of each functional power supply module in the multi-channel and multi-type power management module;

[0044] 102. The intelligent control module runs the firmware, and obtains the voltage or current adjustment range and adjustment scheme according to the judgment result;

[0045] 103. The intelligent control module transmits the voltage or current adjustment range and adjustment scheme to the firmware feedback and control module;

[0046] 104. The feedback and adjustment module adjusts the output voltage or current of the multi-channel and multi-type power management modu...

Abstract

The application discloses an internal performance adjustment structure and adjustment method of a chip in a power supply cabin, and relates to the technical field of power management chips. The internal performance adjustment structure of the power supply compartment chip includes: a multi-channel multi-type power management module, an analog control module, an intelligent control module, and a feedback and adjustment module. This application combines the hardware design and firmware design of the power supply cabin chip, introduces an adaptive intelligent control module, and combines the feedback and adjustment module to solve the independent single multi-channel and multi-output power supply cabin chip that is difficult to solve in the prior art The problem that the adjustment cannot be restored after the performance mismatch can greatly improve the performance index of the multi-channel power management module in the chip.

Description

technical field [0001] The present application relates to the technical field of power management chips, and in particular, to an internal performance adjustment structure and adjustment method of a power supply compartment chip. Background technique [0002] Power management systems generally applicable to consumer electronic devices such as 5G mobile communications, the Internet of Things, and wearable devices (especially wristwatches) need to use voltages or currents in different voltage domains with multiple outputs, so complex systems need to use multiple Power management chips such as multi-channel positive and negative voltage linear voltage regulator LDO chips, charge pump chips and boost / buck conversion chips can output different voltages or currents. The voltage output generally uses positive and negative 1.8V-5V. Regular voltage output. In order to save the area of ​​the PCB board due to the use of multiple independent power management chips and reduce the perfor...
