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.
