Hi team,

can you please help to

1. review their schematic.

2. confirm their inductor selection is fine.

3. let me know if the inductor is overkill.

VIN = 12V

VOUT = 3.8V

IOUT = 3.8A and 4A (designed with Iout = 5A)

INDUCTOR = SPM6530T-2R2M

Thanks,

Kevin

Hi Kevin,

The attached excel tool can be used to check the schematic. Just let me know if there are any concerns after checking with this.

Hi Kevin,

There is a schematic on the DeviceCalculator tab that I think should help you with some of the cells you are unsure of. The DeviceCalculator tab also provides more details for the different Parameters that should also help.
