Single-chip synchronous rectifier saves board space and energy

The Power-SPM™ FPP06R001 from Fairchild Semiconductor® is a monolithic synchronous rectifier that combines integrated MOSFETs of ultra-low on-resistance with superior gate-driver circuitry to minimise MOSFET losses and meet strict energy-saving initiatives such as ENERGY STAR®.

By using the FPP06R001, designers will be able to build power supplies that meet forthcoming Energy Star requirements, which call for operating efficiency above 88% under normal load conditions. Further benefits include board-space savings, due to compact package dimensions and reduced requirement for external components.

Compared to discrete solutions, the device eliminates up to ten discrete components and reduces board space by 20%. Stray inductance is also reduced by 16%, saving thermal dissipation and voltage stress.

The FPP06R001 can be used in the secondary side of the PWM transformer of forward- or bridge-type converters to provide high-current rectification at output voltages from 12V down to 5V. Engineers also have the flexibility to design the secondary side of powersupply systems with reduced parasitic elements to minimise voltage spikes and EMI.
