OUTPUT DIRECT/RATIOMETRIC MSB
A particular feature of the LP55231 is the ratiometric up/down dimming of the RGB-LEDs. In other words, the LED driver PWM output varies in a ratiometric manner. By a ratiometric approach the emitted color of an RGB–LED remains the same regardless of the initial magnitudes of the R/G/B PWM outputs. For example, if the PWM output of the red LED output is doubled, the output of green LED is doubled also.
