Analog Devices Inc. LT3960 Demo Board (DC2686A)

Analog Devices Inc. LT3960 Demo Board (DC2686A) is a 1.3A 8-switch matrix LED dimmer system with an I2C to CAN-physical transceiver featuring the LT3967 and LT3960. The DC2686A Demo Board connects directly to an LED string and LED driver demo circuit, allowing for independent dimming control of up to eight LED channels. A Linduino® One demonstration circuit interfaces with the board and connects in two different ways: directly to a Linduino One demonstration circuit with a QuikEval™ ribbon cable or using the LT3960 break-off board to connect to the I2C master device.

The Analog Devices Inc. LT3960 Demo Board (DC2686A) is designed to be easily configured and interfaced with a compatible low-output capacitance LED driver and LED string. The demo board can easily be directly attached to a buck LED driver or a floating buck-mode LED driver.
