The IS31CG1110-QFLS2 is an integrated circuit (IC) component manufactured by Intersil, which is specifically designed to drive white light-emitting diodes (LEDs) in backlight applications. It offers several key features that make it a versatile and efficient solution for various display backlighting needs.
The IS31CG1110-QFLS2 is designed to provide constant current to a series of LEDs, ensuring uniform brightness across the display. It supports up to 10 LED strings with drive current up to 100mA per string, allowing it to handle a wide range of display sizes. This flexibility makes it suitable for use in a variety of applications, including smartphones, tablets, monitors, and televisions.
One of the notable features of IS31CG1110-QFLS2 is its high-efficiency backlight control. It utilizes a proprietary adaptive boost architecture that optimizes the power efficiency by adjusting the output voltage dynamically, depending on the LED forward voltage and configuration. This results in reduced power consumption, prolonging battery life in portable devices and lowering the overall system energy requirements.
Another key feature is the integrated dimming control functionality. The IS31CG1110-QFLS2 offers a pulse-width modulation (PWM) dimming control, allowing precise and flicker-free adjustment of the LED brightness. Additionally, it supports both analog and digital PWM dimming signals, providing compatibility with various control methods across different devices
