CONTROLLER

DESCRIPTION

The UTC MC34063A is a monolithic regulator subsystem,

intended for use as DC to DC converter. This device contains a

temperature compensated band gap 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.

FEATURES

* Operation from 3.0V to 40V.

* Short circuit current limiting.

* Low standby current.

* Output switch current of 1.5A without external transistors.

* Frequency of operation from 100Hz to 100kHz.

* Step-up, step-down or inverting switch regulators.
