Product Overview

The TL494CD is a PWM Control Circuit 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 error amplifiers exhibit a common-mode voltage range. The dead-time control comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating RT to the reference output and providing a saw tooth input to CT or it can drive the common circuits in synchronous multiple-rail power supplies.
  • Complete PWM power-control circuitry
  • Uncommitted outputs for 200mA 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 5V reference supply with 5% tolerance
  • Circuit architecture allows easy synchronization
  • Green product and no Sb/Br

Applications

Computers & Computer Peripherals, Microwave, Power Management, Consumer Electronics, Communications & Networking
