12V to 3.3V isolation power

how MUCH power? and how CHEAP? the PA3856.004NL from PULSE is reasonably inexpensive ($3.50 each, $2.00 @ 100, etc) and can supply 3.3V@10A from 12V@200KHz flyback in roughly a 0.500" cube off the shelf

Patrick,

As Dan said, can you specify your required power level?

You can search all available TI-Designs and reference designs here:
www.ti.com/.../refdesignsearchresults.tsp

You can click on the tab "Search power designs by parameters", then refine your search by input voltage range, output voltage, output current, DC/AC input, isolated/non-isolated, etc.


E.g. if I search for isolated, DC-input, 10-14V input range, 3.3 V output, i get 47 results, ranging in power from 57 mW to 96 W.

There is likely to be a design in that list that comes close to your spec.

I hope this helps answer your question, if so please click the "verify answer" button.

Thanks,
Bernard
