TL494 - (SMD/SMT) Pulse width modulation control

Description of product

TL494 - (SMD/SMT) Pulse width modulation control - [SOIC]

General Description

The TL494 incorporates all the functions required in the construnction of a pulse-width-modulation(PWM) control circuit on a single chip. Designed primarily for power-supply control, this device offers the flexibility to tailor the power-supply control circuitry to a specific application.


  • Mounting Style: SMD/SMT
  • Complete PWM Power-Control Circuitry
  • Uncommitted Outputs for 200mA Sink or Source Current
  • Output Control Selects Single-Ended or Push-Pull Operation.
  • Internal Circuity Prohibits Double Pulse at Either Output.
  • Variable Dead Time Provides Control Over Total Range.
  • Internal Regulator Provides a Stable 5V (5% Tolerance)
  • Circuit Architecture Allows Easy Synchronization
