DESCRIPTION
The LT ? 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 ±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 V F for
optimum efficiency and open LED faults do not affect the
operation of connected LED strings.
The LT3760 allows a PWM dimming range up to 3000:1
and an analog dimming range up to 25:1. Operating
frequency can be programmed from 100kHz up to 1MHz
using a single resistor or synchronized to an external clock.
Additional features include: programmable maximum
V OUT for open LED protection, a fault flag for open LED,
programmable LED current derating vs temperature, mi-
cropower shutdown and internal soft-start. The LT3760 is
available in a thermally enhanced 28-pin TSSOP package.
