RT8560 Datasheet | Richtek

High Voltage 4 Channel LED Driver General Description The RT8560 is a 60V 4-channel LED driver capable of delivering 30mA to each channel with 15 LEDs (3.6V per diode) total 60 LEDs with one driver. The RT8560 is a current mode boost converter opearated at 1MHz switching frequency, wide VIN range covers from 7V to 40V and the on-chip current switch is rated at 1.5A. The PWM output voltage loop selects and regulates the LED pin with the highest voltage string to 0.9V allowing voltage mismatches between LED strings. The RT8560 automatically detects and disconnects any unconnected and/or broken strings during operation from PWM loop to prevent VOUT from over voltage. The 3% matched...
