NOTES
1. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC.
MIL-STD-217F Notice2 @ Ta=25°C, Full Load (Ground, Benign, controlled environment).
2. Maximum value at nominal input voltage and full load.
3. Typical Value at nominal input voltage and no load.
4. Typical Value at nominal input voltage and full load.
5. Test by minimum Vin and constant resistive load.
6. The output requires a minimum loading on the output to maintain specified regulations. Operation under no-load conditions will not
damage these devices, however they may not meet all listed specifications.
7. For single output models: maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used the
+SENSE should be connected to the +OUTPUT and the -SENSE should be connected to the –OUTPUT.
8. Load regulation for dual output: Minimum load to 100% load balanced on all outputs.
9. Cross regulation for dual output: asymmetrical load 25% / 100% full load.
10. The ON/OFF control function: There are positive (standard) and negative logic (option). The pin voltage is referenced to negative input.
To order negative logic ON/OFF control add the suffix “R” to the part number (Ex: DBW48S5-40R).
11. Heat sink is optional. Please call factory for ordering details.
12. The DBW series can meet EN55022 Class A with an external capacitor in parallel with the input pins.
Recommended: 24Vin: N/A.
48Vin: 2.2µF/100V * 2 PCS 1812 MLCC.
13. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is
Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ.
