Overview
Description The AL8871Q is an LED driver, controller IC for driving external MOSFETs to drive high-current LEDs.
The buck-boost topology controller enables it to efficiently control the current through seriesconnected LEDs.
The 60V capability enables it to be used in a wide range of applications and drive in excess of 15 LEDs in series.
The AL8871Q is a modified hysteretic controller using a patentpending control scheme providing high-output current accuracy.
High-accuracy dimming is achieved through DC control and highfrequency PWM control.
The AL8871Q uses two pins for fault diagnosis.
A flag output highlights a fault, while the multi-level status pin gives further information on the exact...
