1. Introduction
WARNING
Lethal voltage and fire ignition hazard
The non-insulated high voltages that are present when operating this product, constitute a
risk of electric shock, personal injury, death and/or ignition of fire.
This product is intended for evaluation purposes only. It shall be operated in a designated test
area by personnel qualified according to local requirements and labor laws to work with
non-insulated mains voltages and high-voltage circuits. This product shall never be operated
unattended.
This user manual describes the operation of the SSL5031BDB1209 demo board featuring
the SSL5031BTS LED driver in a 100 V to 277 V/18 W non-isolated application.
The SSL5031BDB1209 demo board is designed to drive LED loads from 40 V to 80 V with
a nominal value of 550 V for best THD performance over universal mains input.
The PCB dimensions are compatible with T8 tube applications.
The SSL5031BDB1209 demo board provides a simple and effective solution with a high
Power Factor (PF), low Total Harmonic Distortion (THD), and high efficiency for
Solid-State Lighting (SSL) applications. When, in a buck topology, the LED voltage
exceeds 60 V, it can influence THD at low mains voltages.

2. Safety warning
The demo board input is connected to the 230 V mains. Avoid touching the board while it
is connected to the mains voltage and when it is in operation. An isolated housing is
obligatory when used in uncontrolled, non-laboratory environments. Galvanic isolation
from the mains phase using a fixed or variable transformer is always recommended.

5. Board connections
The SSL5031BDB1209 demo board is optimized for a 100 V to 264 V (AC)/50 Hz to
60 Hz mains supply. It is designed to work with multiple LEDs or an LED module.
Under the expected conditions, the output current is 297 mA when using an LED string
with a 55 V forward voltage (V
F
). The current can be adjusted using resistors R4 and R44.
A 55 V LED voltage gives a good THD performance at 120 V (AC) and 230 V (AC). A
lower LED voltage gives better THD at 120 V (AC). A higher LED voltage does better for
the higher mains voltage.
W1 and W2 are the connections for the mains voltage. J1 (LED+) and J2 (LED) are the
connections for the LED load.
Figure 4
shows the connections.
