Preliminary Datasheet

PULSE-WIDTH-MODULATION CONTROL CIRCUITS

AZ7500F

General Description

Features

The AZ7500F is a voltage mode pulse width modula-

tion switching regulator control circuit designed pri-

marily for power supply control.

Stable 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 Opera-

tion

The AZ7500F consists of a reference voltage circuit,

two error amplifiers, an on-chip adjustable oscillator, a

dead-time control (DTC) comparator, a pulse-steering

control flip-flop, and an output control circuit. The pre-

cision of voltage reference (V ) is improved up to ±

REF

1% through trimming and this provides a better output

voltage regulation. The AZ7500F provides for push-

pull or single-ended output operation, which can be

selected through the output control.

Applications

The AZ7500F is available in standard packages of DIP-

16 and SOIC-16.
