Two MOSFETs in one save space and power
International Rectifier has introduced four SO-8 30V dual HEXFET MOSFETs for synchronous buck convertor applications up to 6A.
International Rectifier has introduced four SO-8 30V dual HEXFET MOSFETs for synchronous buck convertor applications up to 6A. The devices have optimised conduction, switching and body diode characteristics that maximise performance, enabling cooler operation. When compared with similar devices on the market, these new MOSFETs deliver as much as 1% better efficiency over their entire load range, and as much as 2% more efficiency under light loads like those experienced during 'sleep' or 'standby' modes.
Housed in a single SO-8 packages, these dual devices offer a more compact footprint than using pairs of individually packaged transistors for space constrained applications.
They are also suitable for high performance DC/DC synchronous point-of-load (POL) convertors used in advanced telecomms and datacomms systems, as well as general-purpose buck convertors up to 6A.
The IRF7904PbF and the IRF7907PbF each deliver as much as 1% higher efficiency over the entire load range of 6A compared with similar competing devices.
The IRF7902PbF and IRF7905PbF are for high efficiency DC/DC convertors up to 5A, and perform similarly at full load.
However, at 2A, performance is better by as much as 2% versus industry-standard devices.
The IRF7902PbF and IRF7905PbF have similar electrical characteristics, but have different pinout configurations, whereas the IRF7904PbF and the IRF7907PbF match pinouts with the IRF7902PbF and the IRF7905PbF, respectively.
These devices are available either in tubes or tape and reel and are lead-free and are compliant with the Restriction of hazardous substances Directive (RoHS).
