IS31LT3135 MAIN/SUB DUAL-CHANNEL LED DRIVER

IS31LT3135 is a main/sub dual-channel LED driver. When the main channel works，it is a constant current source driving the main LED and the current is set by an external resistor connected to the ISET pin. It needs only 0.1v dropout voltage for 200mA output current. When the sub-channel works, the chip will pull down the sub LED’s cathode to ground. Normally .
