DESCRIPTION
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 is available in 8 pin NSOIC package.
