General Description

TS34063 is a monolithic switching regulator and subsystem intended for use as DC to DC converter. It contains

an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active peak

current limit circuit, drive and a high current output switch. The TS34063 is specifically designed to be

incorporated in step-up, step-down and voltage inverting converter applications. TS34063 is offered in SOP-8 and

DIP-8 package
