Offline, 10 Watt Boost LED Driver (Dimmable) Reference Design


Design files


HVHB LEDs, when driven in a PFC boost configuration, have the advantages of small size, high PFC, high efficiency, low cost, and low complexity. This reference design is triac dimmable, taking universal AC in and drives 3 High Voltage LEDs at 10W.

  • Very small form factor (20mm x 50mm)
  • Near perfect Power Factor Correction
  • Greater than 90% Efficient
  • Triac Dimmable
