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

132VAC/60Hz or driving a 16W analog

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.
