UCC2803: isolation DC/DC select

Hi Feeney,

Based on the diagram you've provided, I don't think I would recommend UCC2803 as a stand alone isolated current sensing solution. Isolated Current Sensing Solution or Design considerations for isolated current sensing are two good TI references which can be realized by either combining a UCC12051-Q1 with any of TI's isolated amplifiers such as AMC1300B-Q1 or consider a combination isolated bias+isolated amplifier such as AMC1400. You can view TI Isolated Amplifiers starting from the landing page here. All TI isolated signal chain ICs requiring primary and secondary side isolated bias can be powered using TI isolated integrated bias modules such as UCC12040, UCC12050 and you can view/select from the TI landing page here.

Thanks for connecting through E2E and I hope this helps guide you to a desired TI solution.

Regards,

Hi Feeney,

I am mostly supporting TI power management ICs which is why your original post came to me. Please repost a new thread with the isolated amplifier part number in the title. Your question will then be redirected to the TI expert supporting these products. Thanks for considering TI.
