Description
General part information
LT3966 Series
The LT3966 is an I2C programmable monolithic boost LED driver with four independent channels. Each channel provides 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.An onboard 8-bit ADC allows measurement of each channel’s output voltage and output current, as well as chip input voltage and two external measurements. In addition, independent shutdown and standby control of each channel provides flexible solutions for multitopology applications.The LT3966 is available in a thermally enhanced 6mm × 6mm 40-Lead QFN package.ApplicationsBacklightingHeads Up Displays
