The Future of Analog IC Technology DESCRIPTION The MP4050 is a constant current LED driver integrated with an internal 500V MOSFET. It is specifically designed for energy efficient and low cost LED bulk replacement applications. MP4050 is designed to drive high-brightness LEDs from an 85VAC to 265VAC line. It is also useable under DC input voltage. The accurate output LED current is achieved by an averaging internal current feedback loop. Constant LED current is delivered quietly by switching the internal MOSFET at a frequency regulated above 22kHz. MP4050 can be directly powered by the high input voltage. An internal high voltage current source regulates supply voltage without external circuitry.
