Error

The Maximum programmable voltage is lower than the maximum 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
