Overview

...ering 30mA to each channel with 10 LEDs (3.
6V per diode), total of 80 LEDs with one driver.
The RT8562 is a current mode boost converter opearated at 1MHz, wide VIN range covers from 6V 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 RT8562 automatically detects and disconnects any unconnected and/or broken strings during operation from PWM loop to prevent VOUT from over voltage.
The 1.
5% matched LED currents on all channels are simply programmed with a resistor or a current sink.
Both analog dimming and digitally controlled PWM dimming are s...
