IR Announces New Family of 30V DirectFET® MOSFETs For Synchronous Buck Converter Design
International Rectifier (IR)® introduced a family of 30V DirectFET® MOSFETs optimized 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 30V HEXFET® power MOSFET silicon and advanced DirectFET packaging technology to achieve what is said to be a 40% smaller footprint compared to a standard SO-8 device, and features a slim 0.7mm profile. The new generation 30V devices achieve very low on-state resistance (RDS(on)) while minimizing gate charge (Qg) and gate-to-drain charge (Qgd) together with ultra-low package inductance to reduce both conduction and switching losses.
"By leveraging our benchmark power MOSFET silicon and DirectFET packaging, the new 30V devices are characterized with very low RDS(on), Qg and Qgd to deliver increased efficiency and thermal performance over the entire load. This also allows operation up to 25A per phase, while maintaining the small form factor of a single control and a single synchronous MOSFET," said Jeff Sherman, IR’s Senior Product Marketing Manager for Enterprise Power Products.
The IRF6724M, IRF6725M, IRF6726M, and IRF6727M are characterized with very low RDS(on) making them well suited for high current synchronous MOSFETs.
The very low Qg and Qgd offered by the IRF6721S, IRF6722S and IRF6722M make these devices ideally suited for control MOSFETs and are available in SQ, ST, and MP footprints for greater design flexibility.
Pricing for the IRF6724MTR1PbF begins at US $1.10; IRF6725MTR1PbF at $1.25, IRF6726MTR1PbF at $1.45 and IRF6727MTR1PbF at $1.50, each in 10,000-unit quantities. The IRF6721STR1PbF begins at $0.60; IRF6722STR1PbF at $0.70 and IRF6722MTR1PbF at $0.75 each in 10,000-unit quantities.
