MP4050A
Feature
DESCRIPTION
The MP4050A is a constant current LED driver with an integrated 500V MOSFET. It is designed specifically for energy efficient and low-cost LED bulb replacement applications.
The MP4050A is designed to drive highbrightness LEDs from a universal AC grid input or DC input. 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 22k Hz.
The MP4050A can be powered directly by the high input voltage. An internal high-voltage current source regulates supply voltage without external circuitry.
Full protections features include integrated thermal current foldback, VCC under-voltage lockout (UVLO), open LED protection (OLP), short-circuit protection (SCP), and overtemperature protection (OTP). These features make the MP4050A an ideal solution for simple, off-line, and non-isolated LED applications.
