SP34063A

1.5A Buck/Boost/Inverting DC-DC Regulator

February 2011

Rev. 2.1.0

GENERAL DESCRIPTION

APPLICATIONS

The SP34063A is a monolithic switching

regulator control circuit containing the primary

functions required for DC-DC converters.

• Battery Charger Circuit

• NICs/Switches/Hubs

• ADSL Modems

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.

• Negative Voltage Power Supply

FEATURES

• Supply Voltage: 3V - 36V

• Current Limiting

• Output Switch Current to 1.5A

• Adjustable Output Voltage

• Operation frequency up to 180KHz

• Low Quiescent Current

• Precision 2% Reference

• Available in 8 pin NSOIC Package

The SP34063A is available in the 8 pin NSOIC

package.
