DATASHEET ISL97691 2.4V LED Driver with Independent Analog and PWM Dimming Controls of 2 Backlights for 3D Application FN7840 Rev.2.00 Sep 8, 2017 The ISL97691 is Intersil’s highly integrated 4 channel LED driver for single cell Li-Ion battery operated mobile displays requiring analog dimming, and for 3D mobile display applications.

It drives four 40mA channels of LEDs up to 26V from an input supply 2.4V to 5.5V.

The ISL97691 will also drive 60mA channels up to 21V at 30% duty for high peak c

ISL97691 Features

* dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for the minimum output regulation. The ISL97691 incorporates extensive protection functions including string open and short circuit detections, OVP, and OTP. The switching frequency can be adju
