General Description

The AZ494B/D is a voltage mode pulse width modulation switching regulator control circuit designed primarily for power supply control.

The AZ494B/D 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 AZ494B/D is capable for push-pull or single-ended output operation, which can be selected through the output control.

Key Features

  • Stable 4.95V for AZ494B or 5V for AZ494D Reference Voltage Trimmed to ±1.5% 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.
