Introduction

AI Translation

The TL494 is used for the control circuit of the PWM switching regulator. The TL494 consists of 5V reference voltage circuit, two error amplifiers, flip flop, an output control circuit, a PWM comparator, a dead time comparator and an oscillator. This device can be operated in the switching frequency of 1KHz to 300 KHz

Features

AI Translation
  • Internal regulator provides a stable 5V reference supply trimmed to so0
  • Uncommitted output TR for 200mA sink or source current
  • Output control for push - pull or single - ended operation
  • Variable duty cycle by deadtime control (pin 4) Complete PWM control circuit
  • On - chip oscillator with master or slave operation
  • Internal circuit prohibits double pulse at either output

Applications

AI Translation
  • Pulse Width Modulated Step - down Converter
