For single output: 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 -Vsense should be connected to its corresponding –OUTPUT. 2. Dual and triple outputs require 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. 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 dual output: asymmetrical load 25% / 100% FL 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 DBXXD3.3-5-33 are specified with 1µF ceramic output capacitors. 6. Please add an external filter at converter input terminals when measuring input reflected ripple, as in Figure 1. L: Simulated source impedance of 12µH. C: Nippon chemi-con KMF series, 220µF/100V 7. The ON/OFF control pin voltage is referenced to the negative input. 8. Switching frequency for dual outputs: master (5Vo) 300KHz slave (3.3Vo) 500KHz 9. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment). 10. Heat sink is optional. Please call factory for ordering details. 11. An external filter capacitor is required for EMC testing. The capacitor should be capable of handing 1A ripple current for 12V/24V/48V models. We suggest: Nippon chemi-con KMF series, 220µF/100V, ESR 90mΩ. 12. Any condition of dual output (3.3V / 5V) rated Iout current, not to exceed 8A of total output current. 13. Maximum value at nominal input voltage and full load. 14. Typical value at nominal input voltage and full load. 15. Test at minimum Vin and constant resistive load.
