GENERAL DESCRIPTION
The ADDC02828SA hybrid dc/dc converter with integral EMI
filter offers the highest power density of any dc/dc converter
available today with its features and in its power range. The
converter with integral EMI filter is a fixed frequency, 1 MHz,
square wave switching dc/dc power supply. It is not a variable
frequency resonant converter. In addition to many protection
features, this converter has system level features that allow it to
