General Description
The 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.
The TS34063 is offered in SOP-8 and DIP-8 package.
