TL494 PWM controller
This guide provides a comprehensive overview of simulating the in LTspice , covering the necessity of behavioral modeling, setting up the simulation, and analyzing the results for switching power supply designs. Introduction to TL494 and LTspice
- CT pin: Sawtooth ~10kHz
- COMP pin: DC level ~2-3V after startup
- OUT1: PWM pulses, duty cycle adjusts to regulate output to 5V
- V(OUT_FB): Regulated ~5V after ~1-2ms
