Demo board description

The UBA20261/2 circuits use half-bridge driver ICs setup to drive standard PLC-18W, G24q-2 socket-based lamps. In addition, similar lamps with a nominal lamp power of 16.5 W can also be driven. The total power drawn from the mains is about 18 W for mains voltages of 230 V or 120 V (RMS). UBA20261/2 boards can 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 (PF): > 0.55
  • Input voltage range: 120 V; 15 %; 60 Hz
  • Input power: 18 W at 120 V
  • Input current: 288 mA/385 mA (boost)
  • Running frequency 44.5 kHz; start frequency 111 kHz
  • Preheat: 0.7 s
