AL8871Q, 60V BUCK-BOOST LED CONTROLLER

.
The AL8871Q is an LED driver, controller IC for driving external MOSFETs to drive high-current LEDs.

Features

* AEC-Q100 Grade 1 Qualified
* Wide Input Voltage Range: 5V to 60V
* Operating Frequency Up to 1MHz
* Analog Dimming Range: 10% to 100%
* 1000:1 PWM Dimming Resolution at 500 Hz
* High Temperature Control of LED Current Using TCTRL
* Fault Repo

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
