TPS92075 - 120VAC, 5W, Phase Dimmable Non-Isolated Buck PFC LED Driver


Design files


The main purpose of this reference design is to demonstrate a high performance and low BOM cost offline phase dimmable Buck PFC LED driver based on TPS92075. This LED driver is designed for converting an AC input to a regulated LED current.

The operating conditions and performance of the reference design are as follows:

  • ●90VAC to 132VAC, 60Hz Input Voltage
  • ●30V LED Voltage
  • ●130mA LED Current
  • ●≥79% System Efficiency
  • ●> 0.95 Power Factor
