Diodes delivers plug-and-play efficiency boost for point-of-load converters

Diodes Incorporated has expanded its DIOFET™ product portfolio with the introduction of two dual channel devices. The DMS3017SSD and DMS3019SSD integrate an optimised control MOSFET with a proprietary DIOFET into a single SO8 package to provide a high efficiency solution 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 typical low RDS(ON of the DIOFET ensures that conduction losses are kept to a minimum, while its forward voltage (VSD) is 25% lower than comparable MOSFET/Schottky solutions, thereby further minimising conduction losses through the body diode during PWM dead-time. The high side MOSFET included in the DMS3017SSD and DMS3019SSD features low gate charge and fast switching, enabling high-side switching losses to be minimised.

These device characteristics enable the DMS3017SSD and DMS3019SSD to deliver a point-of-load conversion efficiency of 94% under full load conditions while at the same time reducing footprint and improving circuit design by reducing the parasitic inductance associated with co-packaged or externally mounted Schottky diodes.

The DMS3017SSD and DMS3019SSD also deliver this performance at a lower operating temperature than comparable solutions. The lower temperature operation of these components can also contribute to an improvement in reliability, since every 10°C reduction in MOSFET junction temperature doubles the lifetime reliability of the point-of-load converter.
