ISL78171 - 50mA Automotive LED Driver

Renesas

Datasheet Details

provide the ISL78171 with the capabilities to design a compact, highly versatile LED backlight for a wide variety of ambient lighting conditions. The integrated peak current mode PWM boost converter operates with a constant frequency and can boost an input voltage range of 4.5V - 26.5V to an output up to 40V and supply six strings of LEDs with up to 50mA each. A dynamic headroom control circuit detects and regulates the highest voltage string to improve efficiency in multistring configurations.
