Diodes releases two new dual channel devices for point-of-load converters
Diodes Incorporated has included two dual channel devices to its DIOFET product portfolio. The DMS3017SSD and DMS3019SSD integrate a control MOSFET with a proprietary DIOFET into a single SO8 package. These devices are suitable 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 low conduction losses. The high-side MOSFET included in the DMS3017SSD and DMS3019SSD features low gate charge and fast switching. It is reported that the DMS3017SSD and DMS3019SSD deliver a point-of-load conversion efficiency of 94% under full load conditions.
The DMS3017SSD and DMS3019SSD operate at a low operating temperature. The low operating temperature improves the reliability of the component since every 10°C reduction in MOSFET junction temperature doubles the lifetime reliability of the point-of-load converter.
