DC-DC converter control circuits

Datasheet

production data

Description

The MC34063A/E series is a monolithic control

circuit which delivers 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 device series is

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

inverting applications.
