GP34063

GP34063 DC TO DC CONVERTER CONTROLLER ISSUED DATE :2004/02/10 REVISED DATE :2005/07/01D 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.
