  • RE: UC3525A: Low Cost High Current Buck Converter

    Hi Mike, In my opinion, both MC34063A and UC3525 are not suitable for this high output current application, because they don't feature the synchronous function, which will cause a large power loss. The reference design PMP10979 is closest to your requirement…

  • RE: LM5119: Input 25-35V, Output 12V/80A.

    Hi Wentao, It is doable. The inductor size would be large. Another option is to use 2*LM5119 (4phase) for 80A design. 4phase design will have better thermal, load transidnet, ripple performance. Attached is the schematic and test result of 4phase reference…
