The ISL97672 is an integrated power LED driver that

controls 6 channels of LED current for LCD backlight

applications. The ISL97672 is capable of driving up to

78 LEDs from 4.5V to 26V or 48 LEDs from a boost

supply of 2.7V to 26V and a separate 5V bias supply on

the VIN pin.

The ISL97672 compensates for non-uniformity of the

forward voltage drops in the LED strings with its 6

voltage controlled-current source channels. Its

headroom control monitors the highest LED forward

voltage string for output regulation, to minimize the

voltage headroom and power loss in a typical

multi-string operation.

The ISL97672 allows direct PWM mode by following the

external signal from 0Hz to 30KHz at 0.4% to 100%

duty cycle and maintaining a typical ±0.7% current

matching between channels.

The ISL97672 features a separate EN pin and

extensive protection functions that flag whenever a

fault occurs. The protections include string open and

short circuit detections, OVP, OTP, thermal shutdown

and an optional input overcurrent protection with fault

disconnect switch.
