AL8843SP-13 LED Driver IC 1 Output DC Regulator Analog PWM Dimming 3A 8-SO-EP

Description

The DIODES™ AL8843 is a hysteresis mode DC-DC step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device can operate from an input supply between 4.5V and 40V and provide an externally adjustable output current up to 3A. Depending upon supply voltage and external components, this converter can provide up to 60W of output power. The AL8843 integrates the power switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. Dimming can be realized by applying an external control signal to the CTRL pin. The CTRL pin will accept either a DC voltage signal or a PWM signal. The soft-start time can be adjusted by an external capacitor from the CTRL pin to Ground. Applying a voltage of 0.3V or lower to the CTRL pin will shut down the power switch.
