Note
1. Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense
FEC40-48T0515 36 – 75 VDC
is not being used, the +Vsense should be connected to its corresponding +OUTPUT
and likewise the sense should be connected to its corresponding –OUTPUT.
2. The triple output required 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 specification
3. 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.
4. Cross regulation for triple output:
Main output 100% load, auxiliary 100%,other auxiliary25% 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%.
5. The models of FEC40-XXD3305 are specified with a 1uF ceramic output capacitors.
6. An external filter capacitor is required for normal operation. The capacitor should be
capable of handing 1A ripple current for 48V/24V models. Power mate suggest:
Nippon chemi-con KMF series, 220F/100V, ESR 90m.
7. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
8. The ON/OFF control pin voltage is referenced to negative input.
9. Switching frequency for dual output:
master (5Vo) 300KHz slave (3.3Vo) 500KHz
10. BELLCORE TR-NWT-000332. Case I: 50% Stress, Te mperature at 40ºC. (Ground
fixed and controlled environment).
11. Heat sink is optional and P/N7G-0026A.
12. Any condition of dual output (3.3V/5V) rated Iout current, not to exceed 8A of total
output currents. The product safety approval pending..
13. Maximum value at nominal input voltage and full load.
14. Typical value at nominal input voltage and full load.
