DESCRIPTION The MHF Series™ of DC/DC converters offer up to 12 watts of power from single or dual outputs in a single package over a the full military temperature range.
Thick film hybrid manufacturing technology produces high levels of miniaturization, giving the MHF Series converters a low profile (0.
330 inch), small board area (1.
65 square inches), and high power density (22 watt/in3).
The parts are packaged in hermetically sealed steel enclosures, making them ideal for use in military, aerospace, and high reliability industrial applications.
elements on both the input and output to help reduce the need for external components.
For information about filtering to meet MILSTD-461’s CE03 test, contact your Interpoint representative.
WIDE VOLTAGE RANGE The MHF Series is designed to provide full power operation over the input voltage range of 16 to 40 volts.
The 15 volt models provide a 19 to 40 volt range.
Operation below 16 volts (or 19 volts for the 15 volt models), including operation in MIL-STD-704E emergency power conditions, is possible with derated output power.
Please refer to the low line drop-out graphs, Figures 9 and 10.
DESIGN METHODOLOGY The MHF converters are switching regulators which use a quasisquare wave, single ended forward converter design with a nominal switching frequency of 600 kHz.
