DESCRIPTION The MFLHP Series™ 28 volt DC/DC converters are rated up to 100 watts output power over a –55° to +100°C temperature range with a 28 Vdc nominal input. On dual output models, up to 70% of the rated output power can be drawn from either the positive or negative outputs. Current sharing allows the units to be paralleled for total power of up to 270 watts. The welded, hermetically sealed package is only 3.005 x 1.505 x 0.400 inches, giving the series an overall power density of up to 67 watts per cubic inch. INHIBIT The MFLHP Series converters have two TTL compatible inhibit terminals (INH1 and INH2) that can be used to disable power conversion, resulting in a very low quiescent input current. An open collector TTL compatible low (
