Hi Sir

May we have isolate power like DCP022415D but we need Vout need 24V?(my customer use in digital I/O)

Chen,
You can use a dual output +/- 12 V in series output connection to get 24 V output such as DCP021212nn. The datasheet describes this method of operation in section 8.4.2.2.

Hi John,

can we use x4 DCD021212nn with 2 series and 2 parallel to achieve 4Watt and 24V out? or have any alternative solution for 4Watt isolated 24V out ?

Best Regards,
Jimmy C

Jimmy,

I do not directly support DCP021212. I know that you can operate them in series and in parallel, but do not know for certain how far you can go with that. Let me see if I can find the correct support person. It will be tomorrow at the earliest.

Hi Chen:

DCP022415D can be used but will require a 24Vout Post linear regulator on Vout .

Parallel DCP022415D unregulated paralled output voltage can be as high as 55 to 60 Volts, with no load. and about 30-35Vout with at 66mA load.

If you have any additional questions on this product my direct contact is tguerin@ti.com
