International Rectifier’s IRF7835PbF and IRF7836PbF are 30-V synchronous buck HEXFET MOSFETs intended for dc-dc synchronous point-of-load (POL) converters. The SO-8 MOSFETs are well suited for systems requiring small size, high efficiency, and improved thermal conduction that results in increased power density. Typical applications include notebook microprocessor power supplies and point-of-load (POL) converters used in high-end servers and advanced telecom and datacom systems.
Reducing total gate charge (Qg) up to 25%, optimizing the body diode losses, and maintaining similar RDS(ON) performance to previous devices helps the MOSFET improve critical light-load efficiency in battery-operated systems by as much as 1.5%.
The IRF7835PbF targets the latest generation of mobile processors requiring a thermal design current of 35 A from a two-phase voltage regulator using one control and two synchronous MOSFETs per phase. It may be used in applications up to 11 A per MOSFET. The IRF7836PbF is designed for power rails using a single control and a single synchronous MOSFET, and it may be used in applications up to 9 A per MOSFET. Both devices comply with the European Union’s Restrictions on Hazardous Substances (RoHS) directive.
