9 Power Supply Recommendations

VDD Input Supply Recommendations

LP5862 is designed to operate from a 2.7V to 5.5V VDD voltage supply. This input supply must be well regulated and be able to provide the peak current required by the LED matrix. The resistance of the VDD supply rail must be low enough such that the input current transient does not cause the LP5862 VDD supply voltage to drop below the maximum POR voltage.

VLED Input Supply Recommendations

LP5862 is designed to operate with a 2.7V to 5.5V VLED voltage supply. The VLED supply must be well regulated and able to provide the peak current required by the LED configuration without voltage drop, under load transients like start-up or rapid brightness change. The resistance of the input supply rail must be low enough so that the input current transient does not cause the VLED supply voltage to drop below LED Vf + VSAT voltage.

VIO Input Supply Recommendations

LP5862 is designed to operate with a 1.65V to 5.5V VIO_EN voltage supply. The VIO_EN supply must be well regulated and able to provide the peak current required by the LED configuration without voltage drop under load transients like start-up or rapid brightness change.
