MC34063A

DC/DC CONVERTER CONTROL CIRCUIT

SPEC NO: DS34063A-00

! FEATURES

! DESCRIPTION

The MC34063A by

^"3V to 30V Input Voltage Operation.

^"Internal 1.6A Peak Current Switch.

^"Internal ±1.8% Reference.

Analog

Integrations

Corporation, an improved second source over the

industrial standard MC34063A, is a monolithic

control circuit containing the primary functions

required for DC/DC converters. The device

consists of an internal temperature compensated

reference, comparator, controlled duty cycle

oscillator with an active current limit circuit, driver

and high current output switch. This device is

specifically designed to be incorporated in step-

down, step-up and voltage-inverting applications

with a minimum number of external components.

The ±1.8% internal reference and low quiescent

current of 1.6mA are among the improvements of

the device over the competition.

^"Low Quiescent Current at 1.6mA.

^"Frequency Operation from 100Hz to 100KHz.

^"Current Limiting.

! APPLICATIONS

^"Saver for Cellular phones

^"DC-DC Converter Module
