MOSFETs for synchronous buck converter designs
9 July 2008
Power Electronics / Power Management
International Rectifier has introduced a family of 30 V DirectFET MOSFETs optimised for synchronous buck converter designs for notebook computers, server CPU power, graphics, and memory voltage regulator applications.
The family of new devices combines IR's latest generation 30 V HEXFET power MOSFET silicon and advanced DirectFET packaging technology to achieve a 40% smaller footprint compared to a standard SO-8 device, and features a slim 0,7 mm profile. The devices achieve on-state resistance as low as 1,2 mΩ while minimising gate charge (Qg) and gate-to-drain charge (Qgd) together with ultra-low package inductance to reduce both conduction and switching losses.
The IRF6724M, IRF6725M, IRF6726M, and IRF6727M are characterised with very low RDS(on) making them well suited as high current synchronous MOSFETs. These new devices have a common MT and MX footprint as previous generation devices to allow easy migration into applications where increased current levels or improved thermal performance is required.
The very low Qg and Qgd offered by the IRF6721S, IRF6722S and IRF6722M make these devices suited as control MOSFETs and are available in SQ, ST, and MP footprints.
