TL594 - PRECISION SWITCHMODE PULSE WIDTH MODULATION CONTROL CIRCUIT

Datasheet Summary

Description

The TL594 is a fixed

frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply.

linear sawtooth oscillator is frequency programmable by two external components,

Features

  • he output pulse width from the maximum percent on.
  • time, established by the deadtime control input, down to zero, as the voltage at the feedback pin varies from 0.5 V to 3.5 V. Both error amplifiers have a common.
  • mode input range from.
  • 0.3 V to (VCC.
  • 2 V), and may be used to sense power.
  • supply output voltage and current. The error.
  • amplifier outputs are active high and are ORed together at the noninverting input of the pulse.
  • width modulator.
