*This is for the TPS657201*
Hi,
My customer wants to switch the buck output to 3.3V instead of the default 1.85V. It looks like every time the battery is removed, the buck output will be reset to 1.85V.
We can write 3.3V to the register, but from the datasheet, it looks like both the DCDC and LDO are enabled as soon as PB_IN is asserted low (which will output 1.85V before we can write 3.3V). I was wondering if holding HOLD_DCDC low during PB_IN will override the enable of the DCDC, or will the 1.85V still output before we write 3.3V to the buck output register?
Thanks,
Josh
