Description

A power module is a power supply device that can be directly mounted on a printed circuit board. It is characterized by providing power for ASIC, DSP, microprocessor memory, FPGA and other digital or analog loads.

Pin Description
Input:
VI+: enter the positive pole
GND: Input negative terminal
EN: Not connected by default. The module is normally on. EN Pin to low level module off
Output:
VO+: output positive voltage
GND: The positive and negative voltages are in common ground
VO-: outputs negative voltage
