UM10512 SSL2109 reference board Rev. 1.1 19 April 2012 User manual Document information Info Keywords Abstract Content SSL2109, buck, controller, reference board, LED driver, LED retrofit lamp 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 .

UM10512 Features

* enable a driver to operate in Boundary Conduction Mode (BCM) with valley switching where the average current in the inductor is the output current. The SSL2109 turns off the MOSFET when the voltage on pin SOURCE reaches 500 mV. If the value of R4 in parallel with R5 is 1, the peak current is limited
