For single output: Maximum output deviation is 10% inclusive of remote sense and trim. If remote sense is not being used, the +sense should be connected to its corresponding +OUTPUT and likewise the -sense should be connected to its corresponding –OUTPUT. 2. Load regulation for dual output: Minimum load to 100% load balanced on all outputs. 3. Cross regulation for dual output: asymmetrical load 25% / 100% full load. 4. 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) 5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment). MIL-STD-217F Notice2 @ Ta=25°C, Full Load (Ground, Benign, controlled environment). 6. Heat sink is optional. Please call factory for ordering details. 7. The DBW series required an external filter to meet EN55022 class A. 8. The dual output required a minimum 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. 9. Output ripple & noise measured with a 0.1µF/50V MLCC. 10. Typical Value at nominal input voltage. 11. Maximum value at nominal input voltage and full load 12. Typical Value at nominal input voltage and full load. 13. Test by minimum Vin and constant resistive load.
