Energy-efficient resonant power controllers
Designing power supplies for products such as telecommunications devices, laptops, game consoles, and LCD and plasma TVs presents increasing challenges for engineers. Size matters, of course: the ever-decreasing real estate in portable electronics and the quest for ultra-thin TVs present the most obvious design hurdles.

Power conditioners offer digital ac meter
The Elite-16 PF E i and Elite-10 E i power management products target the 220 to 240-V markets. The Elite-10 E i power conditioner features a digital ac voltage meter and uses the company's linear filtering technology for suppressing noise across the entire dynamic range. It also features series multistage protection to clamp and dissipate damaging transient voltages, and offers extreme voltage shutdown circuitry to protect against prolonged overvoltages.

Today's civilian, military power conditioning
The increasing complexity of global applications for electronic products in every conceivable commercial environment and power paradigm causes problems similar to those created by the current effort of the military to use up-to-date modern electronics. As a result, there is increasing emphasis on conditioning the input power so that it meets the published requirements of the commercial equipment under the widest possible conditions.

Design interleaving PFC boost power stages
Interleaving isolated and nonisolated power stages is a well understood design technique within the power supply design industry. By far the most widely applied interleaved topology is the multiphase buck, commonly chosen as the power architecture used to meet fast load transient demands of today's high-performance microprocessors and digital signal processors.

Increase Efficiency up to 97 Percent and Simplify Design in Half-Bridge Resonant Converters with Fairchild's 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.

Increase efficiency in switch mode power supply designs with the Power-SPM™ module
The Power-SPM FPP06R001 is a highly integrated synchronous rectification module that increases power efficiency, system ruggedness and space efficiency in power supply designs. Incorporating two PowerTrench® MOSFETs and a high current gate driver in a compact transfer-molded package, the Power-SPM simplifies board design, eliminates up to 10 discrete components and reduces board space by 20 percent. It provides 10 percent lower on-resistance and 16 percent lower stray inductance compared to discrete solutions, which results in lower thermal dissipation and reduced voltage stress. Its high efficiency is instrumental in helping power supply designs meet next generation ENERGY STAR® requirements.
