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.

2. Safety warning
This reference board is connected to a high AC voltage. Avoid touching the reference
board during operation. An isolated housing is mandatory when used in uncontrolled,
non-laboratory environments. Galvanic isolation of the mains phase using a fixed or
variable transformer (Variac) is always recommended. Figure 3 shows the symbols on
how to recognize these devices.

3.1 Connecting to the board
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.
Remark: The maximum rated voltage of the board is 400 V (DC) or 175 V (DC).
