The TPS92411PDDA is a 100V floating MOSFET Switch for offline AC linear direct drive of LEDs with low ripple current. The device is used in conjunction with a current regulator that can achieve a power factor greater than 0.9 to create a LED drive solution with low-ripple current. When properly designed, solution performance is comparable to traditional flyback, buck or boost-based AC/DC LED driver. The approach requires no inductive components, thus saving size. Slew-controlled low-frequency operation of the TPS92411 switches creates very little EMI.
