Description

The KA34063A 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, a driver, and a high current

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

inverting switching regulators as well as for series pass

regulators.
