PULSE-WIDTH-MODULATION CONTROL CIRCUITS

AZ7500B

General Description

Features

The AZ7500B is a voltage mode pulse width modula-

tion switching regulator control circuit designed pri-

marily for power supply control.

Stable 4.95V 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 AZ7500B 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 AZ7500B provides for push-

pull or single-ended output operation, which can be

selected through the output control.

Applications

The difference between AZ7500B and AZ7500C is that

they have 4.95V and 5V reference voltage respectively.

Back Light Inverter

Charger

The AZ7500B is available in standard packages of

DIP-16 and SOIC-16.
