Description:

BUCK AND SEPIC LED CONTROLLER

Features

* Wide Input Voltage Range from 4.7V to 85V
* Pre-Fixed 400kHz Switching Frequency (Factory Set)
* Spread Spectrum Frequency Modulation for Low EMI
* Analog Dimming Range: 1% to 100% ▪ 100% Dimming Level ±3% Current Accuracy ▪ 20% Dimming Level ±12% Current Accuracy

Applications

* The AL8866 operates within a wide input power supply range from 4.7V to 85V. Based on a fixed-frequency, peak current-mode control architecture, the device incorporates spread spectrum frequency modulation and achieves low EMI performance. The AL8866 modulates LED currents with analog or PWM dimmin
