Offline LED Driver dims to zero light intensity without flicker.

Supplied in 8-pin SOIC package, MAX16841 fixed-frequency LED driver for retrofit lamps provides flicker-free dimming from maximum light intensity down to zero intensity with both leading-edge (triac) and trailing-edge (transistor) dimmers. Constant frequency control optimizes efficiency at both low (100-120 Vac) and high (220-230 Vac) AC line voltages. Operating from 90-265 Vac input, driver...
