Description:: 40V, 0.2A 300KHz PWM controller

ECAD Model:

Datasheet:: tl494

Overview

Description
The TL494 device is a pulse-width-modulation (PWM) control circuit designed for power-supply control. It incorporates all the necessary functions on a single chip, including two error amplifiers, an adjustable oscillator, a dead-time control comparator, a pulse-steering control flip-flop, a 5-V precision regulator, and output-control circuits.

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

Applications
Power-supply control
Motor control
Lighting control
Battery chargers
Inverters
