RT8562B
RT8562B is manufactured by Richtek.
High Voltage 8-CH LED Driver
General Description
The RT8562B is a 40V 8-CH LED driver capable of delivering 30mA to each channel with 10 LEDs (3.6V per diode), total of 80 LEDs with one driver. The RT8562B is a current mode boost converter opearated at 1MHz, wide VIN range covers from 4.5V to 24V and the on-chip current switch is rated at 2.5A.
The PWM output voltage loop regulates the LED pins to 0.6V with an auto-adjustment circuit allowing voltage mismatches between LED strings. The RT8562B automatically detects and disconnects any unconnected and/or broken strings during operation from PWM loop to prevent VOUT from over voltage.
