1.5A Boost, Inverting Step-Up Regulator


The SP34063A is a monolithic switching regulator control circuit containing the primary functions required for DC/DC converters.

This device consists of an internal temperature compensated reference, voltage comparator, controlled duty cycle oscillator with active current limit circuit, driver and high current output switch. This device was specifically designed to be used in buck, boost, and voltage-inverting applications with a minimum number of external components.

The SP34063A cis available in an 8-pin NSOIC package.
