DESCRIPTION The MFL Series™ 28-volt DC/DC converters are rated up to 65 watts of output power over a –55°C to +125°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 output. Current sharing allows the units to be paralleled for total power of up to 148watts. 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 43 watts per cubic inch. INHIBIT The MFL 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 and no generation of switching noise. An open collector TTL compatible low (
