1.5A STEP-DOWN/STEP-UP/INVERTING DC-DC CONVERTER AZ34063A

Data Sheet

Jan. 2013 Rev. 1. 6 BCD Semiconductor Manufacturing Limited

General Description

The AZ34063A is a monolithic switching regulator

control circuit which contains the primary functions

required for DC-DC converters. This device consists

of internal temperature compensated reference, voltage

comparator, controlled duty cycle oscillator with active

current limit circuit, driver and high current output

switch.

The AZ34063A is specifically designed as a general

DC-DC converter to be used in Step-Down, Step-Up

and Voltage-Inverting applications with a minimum

number of external components.

The AZ34063A is available in 2 packages: SOIC-8 and

DIP-8.

Features

• Operation from 3.0V to 36V Input

• Low Standby Current

• Current Limiting

• Output Switch Current to 1.5A

• Output Voltage Adjustable

• Operation Frequency up to 180kHz

• Precision 2% Reference

Applications

· Battery Chargers

· ADSL Modems

· Hubs

· Negative Voltage Power Supplies
