The RT8561B is a 40V 8-channel LED driver capable of
delivering 30mA to each channel with 10 LEDs (3.6V per
diode), total of 80 LEDs with one driver. The RT8561B 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 RT8561B automatically
detects and disconnects any unconnected and/or
broken strings during operation from PWM loop to prevent
VOUT from over voltage.资料下载
