MC34063A/MC33063A

SMPS Controller

Features

Description

• Operation from 3.0 to 40V input

• Short circuit current limiting

• Low standby current

• Output switch current of 1.5A without external transistors

• Output voltage adjustable

The MC34063A/MC33063A is a monolithic regulator sub

system intended for use as DC to DC converter. This device

contains a temperature compensated bandgap reference, a

duty cycle control oscillator, driver and high current output

switch. It can be used for step down, step up or inverting

switching regulators as well as for series pass regulators.

• Frequency of operation from 100Hz to 100KHz

• Step up, Step down or inverting switching regulators
