ADC32RF55EVM: Power on switch

Other Parts Discussed in Thread: TSW14J58EVM

Hello team,

My customer is wondering if they should keep the physical power switch in the OFF position, before connecting to the power supply.
I believe the answer is yes, but why? Is it because to make sure the board power up sequence to work properly?

This is because it was written on TSW14J58EVM user guide as below.

Best Regards,

    Kei, the switch can be on or off. It will not impact sequencing or anything like that. The idea is that leaving the switch in the off position provides an extra failsafe and time to check that voltages are correct before the supply is turned on. If the customer ensures that voltages are correct then that is all that matters.
