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 148 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 43 watts per cubic inch. Other output voltages available upon request, including 2 V, 8 V and 54 V single. 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 ( 10 μs. 6. Tested on release from inhibit. 7.
