          This document describes the performance, technical data and the connection of the SSL2109 reference board. The SSL2109 is an NXP Semiconductors controller IC intended to provide a low cost, small form factor LED driver. The reference board is intended to operate at 230 V or 120 V (AC), using an output voltage of 30 V or greater.
          The board is optimized for a 230 V (50 Hz) or 120 V (50 Hz or 60 Hz) mains supply. In addition to the mains voltage optimization, the board is designed to work with multiple LEDs or an LED module with a high forward voltage. Mains connection of the reference
          board is different from other general evaluation/reference boards. Connect the mains to the screw connector J6.
          The SSL2109 is a highly integrated switching mode LED controller which enables Constant Current (CC) driving from the mains input. It is a solution for small to medium LED retrofit lamp application, especially for low-power factor design. The SSL2109 is a buck converter controller suitable for non-isolated, non-dimmable LED retrofit lamps. It can drive long LED strings with, typically 70 V forward voltages. The SSL2109 is intended to operate with higher output voltages, as in modern LED modules.
