Hi,
I'm looking for a cheap low power isolated dc converter circuit. I am looking for an output at 3.3 v with around 10 ma and an input at 3.3 v.
I currently have a basic circuit that outputs far more than it needs and costs a little more than $2 in quantities of a thousand. I would like to get it below $1 in volume if possible. I have found some low power transformers for under a dollar so if I can get the driver circuit costs down it may be possible.
Any advice, circuits or part recommendations for transformers or drivers would be appreciated.
Thanks,
Dan
