Power Supply

1.6kW, 80Plus Platinum Class, High efficiency Server AC-DC Power supply Reference Design


Power supply applications require power MOSFETs with high efficiency, small size and high reliability. Since the release of its first power MOSFET, Toshiba’s power MOSFETs have been widely used in various markets.

In response to the market demand, Toshiba has developed the new high-voltage DTMOS series, the low-voltage U-MOS series, and MOSFETs fabricated using a new material called silicon carbide 「SiC」 contributing to the energy-saving of power supplies.
