MC34063AB - MC34063AC

MC34063EB - MC34063EC

DC/DC converter control circuits

Features

■ Output switch current in excess of 1.5 A

■ 2 % reference accuracy

■ Low quiescent current: 2.5 mA (typ.)

■ Operating from 3 V to 40 V

■ Frequency operation to 100 kHz

■ Active current limiting

Description

The MC34063A/E series is a monolithic control

circuit delivering the main functions for DC/DC

voltage converting.

The device contains an internal temperature

compensated reference, comparator, duty cycle

controlled oscillator with an active current limit

circuit, driver and high current output switch.

Output voltage is adjustable through two external

resistors with a 2 % reference accuracy.

Employing a minimum number of external

components the MC34063A/E devices series is

designed for step-down, step-up and voltage-

inverting applications.
