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-S-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-S-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.
