20V MOSFETs for DC-DC converters in desktop computers and servers

The challenge for distributed power supply engineers is to design a fast switching DC-DC power converter with improved transient response, while still maintaining or increasing efficiency. This has to be achieved in the tight thermal envelope required for reliable system operation and at minimal cost. This paper discusses the use of 20V MOSFETs for the economical design of high efficiency DC-DC power converters, replacing more expensive 30V MOSFETs in desktop computers and servers.
