Variable Frequency DC-DC Converter Controller IC for Step-up or Step-down Voltage Converter

D*CRIPTION
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 p* regulators.
