Overview

DATASHEET ISL97698 High Efficiency 2-Channel White LED Driver for Smartphone Backlighting FN8417 Rev.1.00 Sep 7, 2017 The ISL97698 is a highly integrated 2-channel LED driver for white LED (WLED) backlit TFT-LCD panels.

The device is composed of a synchronous boost converter and two low-side current sinks that are capable of driving an output voltage up to 23.5V and 25mA LED current, per string.

The ISL97698 operates from an input supply of 2.5V to 5.5V.

Key Features

Dynamic Headroom Control that monitors the highest LED forward voltage string to determine the requested boost output voltage. With a controlled low 70mV headroom voltage and low 0.35mA IC supply current, the device provides very high efficiency. The ISL97698 offers 8-bit linear or 11-bit logarithmic controlled analog output current, with dimming control from a PWM, SWIRE, or I2C interface. Internally, the PWM duty cycle, SWIRE, and I2C digital inputs are converted to a DC LED current. This anal.
