Two new dual channel DIOFET devices from Diodes for POL converters

Diodes Inc. has unveiled two new dual channel devices as a part of its DIOFET product portfolio. The DMS3017SSD and DMS3019SSD integrate a control MOSFET with a proprietary DIOFET into a single SO8 package. These devices are suggested for point-of-load converters in consumer and industrial applications.

The low-side DIOFET device integrates a power MOSFET and anti-parallel Schottky diode into a single die. The release says that the device features a low RDS(ON), while its forward voltage (VSD) is 25% lower than comparable MOSFET/Schottky solutions.

The high-side MOSFET included in the DMS3017SSD and DMS3019SSD features low gate charge and fast switching. The relaese says that the DMS3017SSD and DMS3019SSD deliver a point-of-load conversion efficiency of 94% under full load conditions. It is also reported that the DMS3017SSD and DMS3019SSD delivers this performance at a lower operating temperature than comparable solutions.
