DESCRIPTION

The

EV4034-S-00B

Evaluation

Board

demonstrates the capabilities of the MP4034: a

primary-side-controlled, offline, LED lighting

controller that eliminates secondary feedback

components.

The EV4034-S-00B typically drives a 3.5W LED

85VAC to 265VAC at 50Hz.

The EV4034-S-00B has excellent efficiency and

meets IEC61547 surge immunity and EN55015-

conducted EMI requirements. It has multiple

protections, including open-circuit protection,

short-circuit protection, a cycle-by-cycle current

limit, and over-temperature protection.
