External Output Trimming

Output can be externally trimmed by using the method

shown below.

( ) for dual output trim

1. Maximum output deviation is 10% inclusive of remote sense and trim. 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

2. BELLCORE TR-NWT-000332. Case l: 50% Stress, Temperature at 40°C (Ground fixed and controlled environment).

3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.

4. Maximum value at nominal input voltage and full load of standard type.

5. Typical value at nominal input voltage and full load.

6. Test by minimum Vin and constant resistor load.

7. The ON/OFF control pin voltage is referenced to negative input.

8. Heat sink is optional and P/N: 7G-0026A.

9. 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.

10. 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.

11.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%.

12.The models of RP40-XX3.305DG are specified with a 1uF ceramic output capacitors.

13.An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V/24V models.

RECOM suggest: Nippon chemi-con KMF series, 220µF/100V, ESR 90m

Ω.

14.Operating frequency for dual output: master (5Vo) 300KHz slave (3.3Vo) 500KHz.

15.Any condition of dual output (3.3V/5V) rated Iout current, not to exceed 8A of total

output currents. The product safety approval pending.

16.See application notes for EMI-filtering.
