The PCA9633 LED output drivers are 5.5 V only tolerant and can sink up to 25 mA at 5 V.
If the device needs to drive LEDs to a higher voltage and/or higher current, use of an
external driver is required.

INVRT bit (MODE2 register) can be used to keep the LED PWM control firmware the
same (PWMx and GRPPWM values directly calculated from their respective formulas
and the LED output state determined by LEDOUT register value) independently of the
type of external driver. This bit allows LED output polarity inversion/non-inversion only
when OE = 0.
OUTDRV bit (MODE2 register) allows minimizing the amount of external components
required to control the external driver (N-type or P-type device).
