DC-DC Isolated for TPS65381

Other Parts Discussed in Thread: DCP020507

Dear Sirs,

I am looking for an isolated DC-DC converter (Vin=5V - Vout =12V) to feed a TPS65381 with power. In TI website I found a TPS 55010 which fits perfectly with our needs, but looks like the 2W power is too low to feed the TPS65381. In Multirail Power Supply´s manual I could not find the maximum power that can be driven thru this IC, I just found the maximum currents for each output. Someone know what is the TPS65381 maximum power? If is that higher than 2W, does TI have any another isolated DC-DC converter for an input voltage of 5V?

Regards

    you will need a little flyback, but it will result too far expensive compared to the output power level and or the size...

    what about using dcp020507, maybe 2 in parallel to achieve almost 4W on output (as isolated device you can connect more of them in parallel/serial)?

    simple, small, efficient...maybe not the cheapest one, but most depends on what are your critical specifications...
