120Vac Single Stage Non-Dimmable 50W LED Driver Reference Design

This reference design provides a high power ( 50W ) non-isolated: non-dimming LED driver based on the TPS92074. With a nominal input of 120VAC and input range covering 108VAC to 132VAC: the design provides 1 Amp of output current to a 47V nominal stack of LEDs (~16 LEDs). The Buck PFC provides high power factor and low THD.
