The ISL78171EVAL1Z evaluation board is used to evaluate the ISL78171 6-Channel, 50mA automotive LED driver with ultra-high dimming ratio and phase shift control. This board is populated with 60 LEDs in 6P10S (six parallel strings, each string consisting of 10 LEDs in series) configuration to simplify evaluation and testing. The device can function with or without an I2C controller. If it is required to use I2C control for the ISL78171EVAL1Z board, use a generic I2C interface adapter (not supplied with the evaluation board kit) for the purpose of communication. Note that the slave address on the ISL78171 is hexadecimal 58. Refer to the user's guide for jumper settings and power-up instructions
