Part Number: TPS23734 Other Parts Discussed in Thread: PMP23278 We previously referenced the TPS23734EVM circuit design and have already applied it in our product.
Now we have another product that we would also like to design using the TPS23734, but…
Part Number: TPS23734 Other Parts Discussed in Thread: PMP23278 Tool/software: Hello to everyone,
I am designing a POE based on the TPS23734 controller. The EVM implements 5 volt output but I need 12 volts. Can anyone tell me how to do this?
I assume…
Hi Liang,
Thanks for your patience.
Could you replace PQ159 with a PMOS?
ACF converter requires a PMOS for the clamp circuit to work properly.
Please check the reference as following:

Hi Sandeep,
Thanks for reaching out.
I am wondering if you want to use a active clamping forward structure. If so, please refer PMP23278 reference design for the secondary side and the transformer.

Hi Mikel,
Thanks for your reply.
You could use the snubber values in PMP23278 ( https://www.ti.com/tool/PMP23278 ). It is also a 12-V Class-4 ACF circuit.
