INTERNATIONAL RECTIFIER - THE POWER MANAGEMENT LEADER
Single Phase Synchronous Buck Converter Design

Optimized Single-Phase Synchronous Buck Reference Designs targeting at up to 6Amps, 12Amps and 18Amps.

International Rectifier’s new POWIR+ Chipsets, based on IR’s IC and MOSFET products, are supported with highly dependable power management reference designs. The first set of three POWIR+ Chipsets are based on IR’s IR3637S and IR3637AS controllers, targeted at single-phase synchronous buck converter applications in computing and high end consumer applications.

FEATURES
Solid power design expertise built into the reference design to provide predictable electrical and thermal performance representative of a real-life system.
Customization capability offered on all IRPP3637-xxA POWIR+ Chipset reference designs, to meet specific end system requirements.
Full Schematics, bill-of-materials and gerber files are all available.

POWIR+ CHIPSETS USING IR3637S & IR3637AS
The IR3637S and IR3637AS POWIR+ Chipsets feature three standard reference designs optimized for specific power levels (6Amp, 12Amp, 18 Amp) that represent practical designs for real life implementation.

POWIR+ CHIPSETS USING IR3624M
The smaller IR3624M POWIR+ Chipsets feature two standard reference designs ideally for highly compact design. Two specific power levels (5Amp, 12Amp) are offered with this Chipsets.
