Description

          The AL8806 is a step-down DC/DC converter designed to drive °Cs with a constant current. The device can drive up to 9 °Cs, depending on the forward voltage of the °Cs, in series from a voltage source of 6V to 36V. The AL8806 switches at frequency up to 1MHz. This allows the use of small size external components, hence minimizing the PCB area needed. Maximum output current of AL8806 is set via an external resistor connected between the VIN and SET input pins. Dimming is achieved by applying either a DC voltage or a PWM signal at the CTRL input pin. An input voltage of 0.4V or lower at CTRL switches off the output MOSFET simplifying PWM dimming.

Application

            MR16 lampsGeneral illumination lamps  

Features

         30V 1.5A °C drive capability - Drives up to 8 °C in series and provides cost effective solution for MR16 and other 12VAC/DC systems

         5% initial average °C current accuracy - Meets accuracy requirements of most lighting apps at cost effective price and improves inter-channel matching.

         Simple digital PWM dimming with DC dimming on the CTRL pin - Provides flexible scheme to users with different dimming methods: DC for thermal control, PWM for brightness control

         High switching frequency up to 1MHz - Reduces inductor value - reducing size of solution

          Small footprint MSOP-8EP package with only 4 external components - High power density small PCB footprint solution
