UTC MC34063 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 pensated 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.
