power management brochure State of the Art Solutions Exar offers a broad array of power management integrated circuits (IC) 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, leadless DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area. In an effort to respect the environment and reduce the use of hazardous substances, all Exar products have been qualified and released in lead-free versions. 2 Product Description 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. A standard portable application would generally require buck regulators, supervisory ICs, charge pumps, boost regulators and several CMOS LDOs. High power applications like a telecommunications T1/E1 system board may pair several PWM controllers, supervisory ICs, voltage references, and several PNP LDOs for its power management needs. Industry Key Applications Charge Pumps Charge pump technology affords the benefits of a switching regulator without the need for an external inductor. Charge pumps can boost voltage or invert the input to a negative voltage.
