TL494IDRE4 Datasheet

Voltage Mode PWM Controllers


The TL494IDRE4 incorporates all the functions required in the construction 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.The TL494IDRE4 contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator,a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits. TL494IDRE4 Features • Complete PWM Power-Control Circuitry• Uncommitted Outputs for 200-mA Sink or Source Current• Output Control Selects Single-Ended or Push-Pull Operation• Internal Circuitry Prohibits Double Pulse at Either Output• Variable Dead Time Provides Control Over Total Range• Internal Regulator Provides a Stable 5-V Reference Supply With 5% Tolerance• Circuit Architecture Allows Easy Synchronization
