Description

This reference design describes an 18W power supply for driving a string of 13 LEDs (3.3V) at 420mA. The targeted application for this design is T8 fixtures transitioning from standard fluorescent tubes to more efficient LEDs. With an operating efficiency of over 87%, an input voltage range of 90 VAC - 275 VAC, and form factor of 282mm x 18mm, this design provides an ideal solution for this application. Test results provided in this design include EMI tests per CISPR22 Class B standard.

Features
  • Supports a wide input voltage range: 90VAC - 275VAC
  • Unique form factor design is ideal for T8 fixtures (282mm x 18mm)
  • Design has a operating efficiency of ≥87%, PFC over ≥95% at all conditions, and THD maintained to ≤18%
  • Test results demonstrate this design's capability to pass CISPR22 Class B EMI test
  • Test results demonstrate this design's capability to pass EFT and surge tests up to 4kV per IEC61000 standards
