Fairchild's Power-SPM Module Enables Power Supplies To Meet Stringent Energy Star Requirements

San Jose, CA - Fairchild Semiconductor offers power supply designers a Power-SPM module that increases efficiency in power supplies to meet stringent ENERGY STAR requirements. 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. These requirements specify that power supplies must achieve 85 percent or greater efficiency at normal output load conditions.

"Fairchild is at the forefront of solving energy-efficiency challenges. The ENERGY STAR requirement for power supply units will soon increase to 88 percent minimum efficiency at the medium output load condition. This Power-SPM module will be instrumental in helping power supplies meet this requirement," says Donghye Cho, Director of Fairchild's Power Supply System team.

Key advantages of the FPP06R001:

• Integration of two PowerTrench MOSFETs and a high current gate driver replaces up to 10 discrete components.
• Very compact EPM15 package addresses the low-profile requirements of high-end, ultra-slim SMPS designs.
• 10 percent lower on-resistance versus comparable discrete solutions.
• 16 percent lower stray inductance reduces unwanted high voltage spikes, which increases design margin and lowers EMI.
• Excellent high current driving capability with its built-in buffer IC.

The Power-SPM module is part of a comprehensive portfolio of Fairchild's energy-efficient products. From 1W to 1200W, Fairchild's solutions meet regulations that are of paramount concern to today's designers such as ENERGY STAR, PFC requirements, the <1 Watt Initiative and other green regulations. Fairchild recognizes that today's applications require increased efficiency even as their product features multiply and the product itself shrinks in size. Fairchild continues to develop cutting-edge solutions that integrate functionality and advance packaging technologies to improve efficiency and thermal characteristics while saving board space and reducing component count.

The FPP06R001 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
