Error

The Minimum programmable voltage is higher than the minimum Baseline Set Point Voltage. This is not allowed by the USBPD Standard.

The USBPD Standard specifies the required Programmable range to be advertised as a function of the maximum PDO voltage.

VOPPMIN = 3.3 V (constant).

VOPPMAX = 5.9 if PDP<=15, VOPPMAX = 11 if 15<PDP<=27, VOPPMAX = 16 if 27<PDP<=45, VOPPMAX = 21 if PDP>45
