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 SSL5031BDB1207 120 V 9 W eco-THD
non-dimmable LED driver featuring the SSL5031BTS. The reference board has a A19
LED lamp compatible form factor. The buck converter topology provides a simple and
efficient solution for mains non-dimmable LED recessed light applications.
The reference board complies with EMI and safety regulations.
Figure 2
shows the dimensions of the SSL5031BDB1207 demo board. The design of the
board allows enough headroom for the board to fit into a A19 lamp base.
Figure 3
shows the SSL5031BDB1207 assembled top and bottom views.
2. Safety warning
The demo board input is connected to the 120 V mains supply. 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.
Figure 1
shows the symbols on how to recognize these devices.
