DEMO BOARD
To allow an easy evaluation of the device, a P.C. board dedicated to lamp ballast application has been de-
signed.
Fig.11 shows the electrical schematic of a typical ballast application, while the PC and component layout is giv-
en in Fig12. This application has been designed to work with both the 110+/-20%V and the 220 +/- 20%V mains
by means of a voltage doubler configuration at the bulk capacitor. The ballast inductance and the operating fre-
quency are especially designed for a 18 W Sylvania De-luxe T/E type bulb. The PTC for preheat at the start up
and the two back to back synchronization diodes, makes this application easy to implement and safe in opera-
tion.
