DESCRIPTION

The

EV4088-S-00A

Evaluation

Board

is

designed to demonstrate the capabilities of

MP4088. The MP4088 is a highly integrated

TRIAC dimmable LED driver with high power

factor. It is specifically designed for high-line

input (230VAC), no-isolated, TRIAC-dimmable

LED lighting applications, especially for the low

cost and small form factor applications.

The MP4088 integrates a 500V MOSFET. Only

a single winding inductor is required to realize

the solution. It features MPS’s proprietary

hybrid operation mode which is designed to

achieve good dimming performance.

The EV4088-S-00A is typically designed for

driving a 5.5W TRIAC dimmable LED bulb with

265VAC, 50Hz.

The EV4088-S-00A has an excellent efficiency

and

meets

IEC61547

surge

immunity,

IEC61000-3-2

Class

C

harmonics

and

EN55015 conducted EMI requirements. It has

multi-protection

function

as

over-voltage

protection;

output

short-circuit

protection,

thermal shut down, etc.
