TYPICAL PERFORMANCE CHARACTERISTICS (continued)
All curves taken at VIN = 5V with configuration in typical application for driving one red (OSRAM LRW5AP-KZMX), one green
(OSRAM LTW5AP-LZMY) and one blue (OSRAM LBW5AP-JYKX) LEDs with I_OUT per channel = 1.5A under T_A = 25°C,
unless otherwise specified.
RED Efficiency vs V_IN @ T_A = 25°C
GREEN Efficiency vs V_IN @ T_A = 25°C
