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 10VTYP, 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.
