Has someone ever tried to replace a Richtek RT3602AH with an NCP81206A (or NCP81236A)?
Or can someone give me advices to proceed or not?
I have two boards, one working Lenovo NM-C121 with CPU i3 (RT3602AH used in Single Phase) and one not-working HP Quanta 0PA with an i5 (broken RT3602AH in 2-phase mode with RT9610C to control the second phase).
Since I can't receive a new RT3602AH soon, and I have two new NCPs (one 81206A and one 81236A) I thought about swapping the two ones, putting the NCP81206A on the NM-C121 and the RT3602AH on the HP board that needs 2-phase work.
Comparing datasheets of the Richtek and OnSemi ICs, I see that they have almost the same 52 pins (same VCC, GND, EN, PWM etc pins), and they are made for IMVP8 platforms, but the Richtek one has pin 2 5 and 6 designed to regulate some inner settings, called SET1 SET2 and SET3, and in the application circuit they are only connected to a few resistors.
Instead, the OnSemi ones 2, 5 and 6 have other functions called DIFFOUT, ILIM and CSCOMP.
According to you, would this swap be possible without risking to fry the CPU on the Lenovo NM-C121 board?
