Demo board description

The UBA20260 circuit is a half-bridge driver IC setup to drive a typical 23 W burner with a lamp current of about 240 mA. Similar lamp types with a nominal lamp power of 20 W can also be driven. The total power drawn from the mains is about 23 W at a nominal mains voltage of 230 V or 120 V (RMS). The UBA20260 board can easily be configured to drive different Compact Fluorescent Lamps (CFL) of different power ratings. Driving different CFL is possible by changing the inductor tap and installing a different lamp capacitor.

Features

  • Step dimming set to: 100 % / 38 % / 13 % / 3 % of the lamp current
  • 1.5 x lamp current boost, set for 50 s
  • Power factor: > 0.55
  • Input voltage range: 230 V; 15 %; 50 Hz
  • Input power: 23 W at 230 V
  • Input current: 179 mA / 228 mA (boost)
  • Running frequency 45 kHz; start frequency 111 kHz
  • Preheat: 0.7 s
