DESCRIPTION
The EV4031-S-00A Evaluation Board is
designed to demonstrate the capabilities of
MP4031. The MP4031 is a primary-side-control
offline LED lighting controller which can achieve
high power factor and accurate current for
either Triac dimmable or analog dimmable LED
lighting application. It works in boundary
conduction mode for reducing the MOSFET and
Diode switching losses.
The EV4031-S-00A is typically designed for
either driving a 16W Triac dimmable LED bulb
with 30V
TYP
, 530mA LED load at 108V-
132VAC/60Hz or driving a 16W analog
dimmable LED bulb with 30V
TYP
, 530mA LED
load at 108-305VAC.
The EV4031-S-00A has an excellent efficiency,
can pass 3kV surge test, and meets IEC61000-
3-2 Class C harmonics and EN55015
conducted EMI requirements. It has multi-
protection function as over-voltage protection,
over-current protection, cycle by cycle current
limit, etc.
