General Description

The TS3063 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 TS3063 is specifically designed to be incorporated in step-up, step-down and voltage inverting converter

applications. The TS3063 is offered in SOP-8 and MSOP-8 package
