If peripheral is power-supply voltage sensitive, give peripheral own power-supply.
Peripheral own power-supply may take from SYS_5V or VDD_3V3B. I did not have time to find a dev board with (I2C) variable voltage output. SYS_5V cannot be used for software controlled variable output because of TPS65217C: SYS_5V is output switched between input VDD_5V jack-in and input USB_DC PC USB (and input BAT) the highest voltage input is switched on.
