SSL5301DB1215 120 V 13 W buck converter
10. Tuning options
A footprint for TVS diode D6 is available for different classes of surge protection.
An optional footprint for capacitor C6 is available in case of noisy R
mains
.
Use the optional capacitor C7 to improve conducted EMI performance in the application.
Add resistor R19 for dimming curve selection (see SSL5301T data sheet for more
information). Connect resistor R21 to enable the buck-boost topology. When resistor R21
is connected, R20 must be disconnected. Also check the mode selection resistors R3 and
R4 if the topology is changed (see table 4 in the SSL5301T data sheet for more
information about the selection of different modes).
Use optional resistors R17, R18 and diode D5 to provide start-up current to certain types
of smart dimmer.
