UTCMC34063 LINEAR INTEGRATED CIRCUIT
DC TO DC CONVERTER
CONTROLLER
DESCRIPTION
The UTC MC34063 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.
