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
string with a 10V
TYP
, 350mA LED load from
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.
