1.6 kW Server Power Supply (Upgraded)

Thanks to Toshiba’s latest power devices and digital isolator, this 1U size and 12 V output 1.6 kW server power supply achieves higher efficiency at whole load than the existing reference design which uses the same circuit topology. Design files and guides for circuit design and operation are available as reference design.
