Summary of PIC12F629 PWM SMPS CONTROL

This project implements a 25kHz PWM-controlled SMPS using the PIC12F629 microcontroller to drive BUK555 MOSFETs. Designed for 12V battery operation, it utilizes an EI33 transformer salvaged from an ATX power supply. The circuit successfully delivers up to 50W of output power, with secondary windings customized based on specific requirements.

Parts used in the PIC12F629 PWM SMPS Control:

  • PIC12F629 microcontroller
  • BUK555 MOSFETs
  • EI33 transformer (recovered from ATX SMPS)
  • 12V battery
  • GP0 and GP1 output pins
