Features & Applications

The AL8805W5-7 is a part of AL8805 series LED Drivers. It has operating temperature ranging from –40°C to +125°C,it comes in SOT-25 package.

The AL8805 is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 8 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 6V to 30V. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

The AL8805 switches at frequency up to 1 MHz. This allows the use of small size external components, hence minimizing the PCB area needed. Maximum output current of AL8805 is set via an external resistor connected between the VIN and SET input pins.
