TPS23754: Dual input with current sharing

Denny Huang

Part Number: TPS23754
Other Parts Discussed in Thread: UCC29002, PMP20859, TPS23730EVM-093

Dear team

The customer would like to use to PD input(TPS23754) with current sharing ic(ucc29002). Dose TI have reference design?

For 50W(25+25) application. Dose TI have reference design like PMP20859 or another circuit could mortify to achieve 50W output power.

Many thanks

Hey Denny,

For 2x25W at 12V, if they want both ports to be compliant I think the easiest thing to do is to use a PDS design that we have already proven out with customer. I will send it to you in email.

Additionally, if they need 51W, can they consider the TPS23730EVM-093?

If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
