Hi Darwin，thanks for help，our customer also has same question as follow，could you help to check it，tks！
1. because they only design as Vout：12V/2A ，so they want to konw why the Q3 and Q5 use so large margin in the recommended BOM？，
2. the schematic…
Take a look at TPS23754. It is a type 2 PD and dc/dc controller designed for 25W, 2 pair applications. The minimum current limit for the PASS FET is 850mA. For 45W, you would need 53V in at 850mA.
TI has a couple of high power reference designs using…
