Intersil ISL97687IBZ

DC DC 控制器9V32V160mA

Overview

The ISL97687IBZ is a PWM controlled LED driver that supports four channels of LED current, for Monitor and TV LCD backlight applications. It is capable of driving 160mA per channel from a 9V to 32V input supply, with current sources rated up to 75V absolute maximum.

The ISL97687IBZ has an advanced dynamic headroom control function that monitors the highest LED forward voltage string, and regulates the output to the correct level to minimize power loss. This proprietary regulation scheme also allows for extremely linear PWM dimming from 0.02% to 100%. The LED current can also be switched between two current levels, giving support for 3D applications. The ISL97687IBZ incorporates extensive protections of string open and short-circuit detections, OVP, and OTP.
