6 / 13 page L6569 L6569A 6/13 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. part value R1 15ohm 1W R2, R3 22 ohm R4 27K R5 100K 1/2W R6 47ohm R7, R9 180K R8 120K 1/2W D1 18V zener D2, D3 BYW100-100 D4,D5,D6,D7 1N4007 D8 1N4148 C1 560pF 50V C2, C5 47 µF 250V C3 4.7 µF 25V C4 100nF 50V C6 100nF 250V C7-C8 8.2nF 630V C9 470pF 630V RV1 PTC 150ohm Q1, Q2 STD2NB50-1 L1 2.4mH |
