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.
