Exar expanded its offering of AC step driver solutions for LED bulbs with the introduction of the XR46073 – a two-step LED current controller with improved line regulation primarily for A19 LED bulb applications. The IC integrates two steps of current control to the LED strings, greatly improving the line regulation of the circuit by monitoring the line voltage and adjusting LED drive current proportionally. Also included in the 2 x 2 mm DFN package is over-voltage protection and over-temperature protection. During an over-temperature condition, the XR46073 smoothly and continuously reduces current to the LED string, reducing power dissipation in the process, until temperatures have stabilised at an acceptable level.
