DC TO DC CONVERTER CONTROLLER
Description
The GSC34063 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.
