UBA2017P 2 x 28 W T5 demo board with passive PFC

Archived content is no longer updated and is made available for historical reference only. This 230 V (AC) demo board drives two 28 W T5 lamps featuring the UBA2017P. No MOSFET is used for the PFC stage but improved vally fill and continious input current techniques are used to comply with IEC standards. This demo board can easilly be modified to drive one T5 lamp with a power of either 21 W, 28 W or 35 W while complying with IEC mains harmonics requirements.
