INTERNATIONAL Rectifier, represented by Arrow Electronics , has introduced the IRF7835PbF and IRF7836PbF, 30V synchronous buck HEXFET MOSFETs for dc-dc synchronous point-of-load (POL) converters.

The SO-8 synchronous MOSFETs are designed for applications where requirements of small size, high efficiency and improved thermal conduction resulting in increased power density are desired, such as notebook microprocessor power supplies and point-of-load (POL) converters used in high-end servers, as well as advanced telecom and datacom systems.

Reducing total gate charge (Qg) up to 25%, optimising the body diode losses and maintaining similar RDS(on) performance as previous devices, improves critical light-load efficiency in battery-operated systems by as much as 1.5%.

The new IRF7835PbF targets the latest generation of mobile processors requiring a thermal design current of 35 amps from a two-phase voltage regulator using one control and two synchronous MOSFETs per phase.

The device may be used in applications up to 11A per MOSFET. The new IRF7836PbF is designed for power rails using a single control and a single synchronous MOSFET, and may be used in applications up to 9A per MOSFET.

These devices are RoHS-compliant.
