Analog Devices LT3966

Beschreibung

The LT®3966 is an I2C programmable monolithic boost LED driver with four independent channels. Each channelprovides a 60V current mode boost converter with an internal 1.6A DMOS power switch, as well as internal and external analog and PWM dimming features. I2C programmable features include a 13-bit (8192:1) digital PWM generator, 8-bit analog dimming DAC, and flexible fault reporting and handling.
