AZ494 Datasheet Voltage Mode Dual Output Pwm Controller

Manufacturer: Diodes Incorporated

Overview: NOT REMENDED FOR NEW DESIGN CONTACT US AZ494 VOLTAGE MODE DUAL OUTPUT PWM.

General Description

The DIODES™ AZ494 is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control.

The AZ494 consists of a reference voltage circuit, two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) parator, a pulse-steering control flip-flop, and an output control circuit.

The precision of voltage reference (VREF) is improved up to ±1% through trimming and this provides a better output voltage regulation.

Key Features

  • Stable 4.95V/5V Reference Voltage Trimmed to 1.0% Accuracy.
  • Uncommitted Output TR for 200mA Sink or Source Current.
  • Single-End or Push-Pull Operation Selected by Output Control.
  • Internal Circuitry Prohibits Double Pulse at Either Output.
  • Complete PWM Control Circuit with Variable Duty Cycle.
  • On-Chip Oscillator with Master or Slave Operation.
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2).
  • Halogen and Antimony Free. “Green” Device (Note 3) Applica.
