Features & Applications
Exar offers a broad array of power management integrated circuits (ICs) that are used in a wide variety of end applications.

Exar’s state of the art solutions provide high efficiency, low quiescent current, small size and the industry’s best price/performance ratio.

Many of Exar’s most advanced power management ICs are offered in thermally enhanced, lead-free DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area. 

Exar power management products can be used as stand alone solutions but are designed to be used together to create a complete power management system.  This product group includes low drop out linear regulators (LDOs), DC to DC switching regulators, PWM controllers, charge pumps, and microprocessor supervisors.

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.
