Can you suggest to sofirn to bump up the inductor value to 1uH ? 0.47uH is too low for the MP3432 and even with higher DCR the higher inductance will improve efficiency.
Pictures of the driver from Haukkeli showing the 6060 0.47uH inductor.
Edit : efficiency estimates from MPS DC-DC designer, with a 6060 0.47uh inductor (2.6mΩ), 3Vin 6.5Vout6A :
4Vin :
