Descriptions

TL494 is a PWM controller IC used for power electronics circuits. It comprises of on-chip two error amplifiers an oscillator with adjustable frequency feature, an output flip-flop having pulse steering control, and an output control circuit with feedback.

 

Features

  • Built-in PWM control Channels
  • Current sink and source rating: 200mA
  • Dual output selectable operations: Single-ended or push-pull operation
  • Deadtime control feature: Variable range
  • Easy synchronization with other circuits
  • PWM outputs: 2
  • Fixed frequency oscillator

 

 Specifications

  • Supply voltage ( Vcc): up to 41 volts
  • Maximum output current for both PWMs: 250mA
  • Output voltage at collector pins: 41 volts
  • Temperature range: -65 to 150 degrees
