Digitally-controlled switching power supply circuit diagram based on single chip microcomputer

Single chip microcomputer STM32L151CCU6

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

Overview:
This paper adopts the asymmetric half-bridge power converter based on the single chip microcomputer KA3525 PWM control chip, and adopts the 16-bit Lingyang single-chip microcomputer as the numerical control core, and improves the output precision and efficiency of the power supply through its built-in D/A output modulation PWM. It is convenient for users to operate and realizes the digitally controlled switching power supply based on single chip microcomputer.
