LT3760
8-Channel Г— 100mA
LED Driver
Description Features The LTВ®3760 is an 8-channel LED driver with a step-up
DC/DC controller capable of driving up to 45V of LEDs.
Each channel contains an accurate current sink with В±2%
current matching. Channels follow a master programmable
current to allow between 20mA to 100mA of LED current
per string. Channels can be paralleled for higher LED
current. Output voltage adapts to variations in LED VF for
optimum efficiency and open LED faults do not affect the
operation of connected LED strings. Up to 45V of LEDs Г— 100mA, 8-Channel LED Driver
