  Part Number: PMP20178 I used PMP20178 as a reference, and I find that the high side MOS and low side MOS are different, can I use the same MOS for high side and low side.I also find there is a diode STPS6M100DEE-TR between sw and PGND, and I don't understand…

  Sachin, This spec may be difficult to meet with a single-phase solution. But if this is a requirement I'd recommend starting by looking at PMP20178 and scaling up the inductor and FETs. You can check the rise-times and fall-times of the FETs with the…
