Fairchild Semiconductor’s Green FPS™ Power Switch Simplifies Design and Increases Efficiency up to 97 Percent in Half-bridge Resonant Converters up to 450W

Fairchild Semiconductor's Green FPS™ Power Switch Simplifies Design and Increases Efficiency up to 97 Percent in Half-bridge Resonant Converters up to 450W

Fairchild Semiconductor's (NYSE: FCS) highly integrated Green FPS power switch, the FSFR2100, increases power efficiency and system reliability, and reduces valuable design time in resonant converter designs such as telecom power, high end audio amplifiers, large size laser printers and LCD and PDP TV power supplies.

Offering a “system-in-a-package” approach that integrates everything necessary to build reliable and efficient resonant converters, this power switch integrates a pulse-frequency-modulation (PFM) controller with a high voltage gate driver circuit and two fast recovery MOSFETs (FRFET®) along with soft-start, burst operation and important protection features into a thermally-efficient 9-SIP package
