AZ494

VOLTAGE MODE DUAL OUTPUT PWM CONTROLLER

Description

Pin Assignments

(Top View)

The AZ494 is a voltage mode pulse width modulation switching

regulator control circuit designed primarily for power supply control.

1IN+

1IN-

2IN+

2IN-

The AZ494 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 precision of voltage reference (V_REF) is improved up to

±1% through trimming and this provides a better output voltage

regulation. The AZ494 provides for push-pull or single-ended output

operation, which can be selected through the output control.

The difference between AZ494A and AZ494C is that they have 4.95V

and 5V reference voltage respectively.

The AZ494 is available in standard packages of PDIP-16 and SO-16.
