The ISL97683IRTZEVALZ evaluation board provides a complete testing platform for the ISL97683 3-channel LED driver.

The ISL97683 is a highly integrated 3-channel LED driver that is suitable for medium size TFT-LCD backlights. This part can drive multiple channels of LEDs from inputs as low as 4V to outputs of up to 45V. It can also operate from inputs as low as 3V to outputs of up to 26.5V in bootstrap configuration.
