Product 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 EV4050A-J-00A Evaluation Board is designed to demonstrate the capabilities of MP4050A as an off-line, non-isolated LED driver which can load 40V/115mA LEDs in universal input voltage (85VAC to 265VAC, 50Hz/60Hz).

The EV4050A-J-00A has an excellent efficiency and meets IEC61000-4-5 surge immunity and EN55015 conducted EMI requirements. It has various protections, like integrated thermal current foldback, VCC under-voltage lockout (UVLO), open LED protection (OLP), short-circuit protection (SCP), and over-temperature protection (OTP). All of there features make MP4050A an ideal solution for simple, off-line and non-isolated LED applications.

EV4050A-J-00A is the evaluation board for MP4050A TSOT23-5 package.

Non-Isolated, High Brightness LED Driver with Enhanced Thermal Feature

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 high-brightness 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 22kHz. 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 over-temperature protection (OTP). These features make the MP4050A an ideal solution for simple, off-line, and non-isolated LED applications.
