Analog Devices LT3965-1
the LT3965-1 is initialized with all switches on (LEDs off)The LT3965/LT3965-1 uses the I2C serial interface to communicate with the microcontroller. Each of the eight channels can be independently programmed to bypass the LED string in constant on or off, or PWM dimming with or without fade transition. The LT3965/LT3965-1 provides an internal clock generator and also supports external clock source for PWM dimming.| Part No. | LT3965-1 |
