Abstract
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.

9. Active bypass
An increased value for the inrush current resistor protects the board from damage with
phase cut dimmers, however lowers the efficiency. If a higher PF is not required, but
leading-edge dimmer compatibility and high efficiency are important, the active bypass
option is available. In this circuit, the inrush current resistor is bypassed using a Silicon
Controlled Rectifier (SCR). See Figure 11.
Table 4 shows the results when active bypass is used.
