NOTES

1.

The JRW Series 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.

2.

Please add an external filter at converter input terminals when measuring input reflected ripple current (See Figure 1).

L: Simulated source impedance of 12uH C: Nippon chemi-con KMF Series 47uF/100V.

3.

The ON/OFF control pin voltage is referenced to –Vin.

To order negative logic On/Off control add the suffix “R” (Ex: JRW24S5-2000R).

4.

BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment).

5.

“I” Version is more efficient; therefore, it can be operated over a more extensive temperature range than the standard version. Please add the suffix “-I”

for industrial grade temperature range models.

6.

Heat sink is optional, please consult factory for ordering details.

7.

The JRW Series meets 55022 class B with external components connected before the input pin to the converter.

8.

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

9.

Typical value at nominal input voltage and no load.

10. Tested at minimum Vin and constant resistive load.
