The EV4027-J-01A Evaluation Board is designed to demonstrate the capabilities of MP4027. The MP4027 is a primary-side-control offline LED lighting controller which can achieve high power factor and accurate LED current for an isolated lighting application in a single stage converter. It works in boundary conduction mode for reducing the MOSFET and Diode switching losses.
The EV4027-J-01A is typically designed for driving an isolated 7W A19 LED bulb with 20VTYP, 350mA LED load at universal input (90V~265VAC, 50/60Hz).
The EV4027-J-01A has high performances in efficiency, line/load regulation and meets IEC61547 surges, IEC61000-3-2 Class C harmonics and EN55015 conducted EMI. It has multi-protection function as over-voltage protection, short-circuit protection, primary-side OCP, NTC, etc.
