If remote sense is not being used, the +Vsense should be connected to its corresponding +OUTPUT and likewise the sense should be connected to its corresponding -OUTPUT. Triple outputs requires a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specifications Load regulation for triple output: Main output (V1): 10 to 100% with 10% to 100% balanced on auxiliaries. Auxiliary outputs (V2 and V3): 10% to 100% balanced on all outputs. Cross regulation for triple output: Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%. Auxiliary outputs (V2 and V3): main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other auxiliary 25% to 100%. The models of FEC40-XXD3305 are specified with a 1uF ceramic output capacitors. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models. Astrodyne suggests: Nippon chemi-con KMF series, 220µF/100V, ESR 9OmÙ. Simulated source impedance of 12uH. 12uH inductor in series with +Vin. The ON/OFF control pin voltage is referenced to negative Input. Switching frequency for dual output: Master (5Vo) 300KHz; Slave (3.3Vo) 500KHz BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 4OºC. (Ground fixed and controlled environment). Heat sink is optional and P/N: 7G-OO26A. Any condition of dual output (3.3V/5V) rated lout current, not to exceed 8A of total output currents. Maximum value at nominal input voltage and full load. Typical value at nominal input voltage and full load. Test by minimum Vin and constant resistor load.
