mode
Accuracy: ±2% per channel at I(IOUTX) > 30mA
Accuracy: ±2.5% per device at I(IOUTX) > 30mA
? Use multiple ICs or multiple channels of a single IC
in parallel to achieve higher current
? Low voltage drop
Maximum voltage drop: 400mV per channel at
60mA
Maximum voltage drop: 0.9V per channel at 150mA
Each channel performs PWM dimming independently
? Open and short circuit LED detection with anti-burr
pulse timer
? Voltage feedback of each channel LED lamp string
is used for single LED short circuit detection
? Independent fault pin for single LED short circuit
