The ISL97677 can operate in multiple modes of operations. It can be controlled by SMBus/I2C communications and an external PWM dimming signal with currents matching of 1% across all ranges. The ISL97677 features extensive protection functions that include string open and short circuit detections, OVP, and OTP. The fault conditions will be recorded in the Fault/Status register. There are selectable short-circuit thresholds and the switching frequency can be programmed between 500kHz and 1.5MHz.
