8.3.2 Power Supply Recommendations

VIO Input Supply Recommendations

LP5866 is designed to operate with a 1.65V to 5.5V VIO_EN voltage supply. The VIO_EN supply must be well regulated and can provide the peak current required by the LED configuration without voltage drop under load transients like start-up or rapid brightness change.
