Laptop HP Omen 16-b
Płyta: DA0G3KMBCG0
CPU: SRKT3
GPU: GN20-E5-A1
KBC: IT5570E-256

Proszę o pomoc w zidentyfikowaniu układów oznaczonych CP3 (foto). Są to drivery mosfetów pracujące w zasilaniu CPU z kontrolerem NCP81307.

looks like DFN8 Synchronous Buck MOSFET Driver from Onsemi ...model with closest Specific Device Code CR* is NCP81258...your Specific Device Code is CP*, but couldnt find it.

Are You sure? How did You figure that out?

Yes, I'm sure. Did you even open the attached datasheet?

According to the datasheets, this chip looks practically identical, so you can try.
If you are going to use NCP81151 (without "B"), I recommend replacing all four chips with the same ones, as this chip works in a multi-phase power supply.
