GENERAL 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 the 8 pin NSOIC
package.
