Description

The GP34063 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.
