108Vac~305Vac, 30V/530mA Primary-side-control with Active PFC TRIAC and Analog Dimmable LED Driver EVB
The EV4031-S-00A Evaluation Board is designed to demonstrate the capabilities of MP4031. The MP4031 is a primary-side-control offline LED lighting controller which can achieve high power factor and accurate current for either Triac dimmable or analog dimmable LED lighting application. It works in boundary conduction mode for reducing the MOSFET and Diode switching losses.
The EV4031-S-00A is typically designed for either driving a 16W Triac dimmable LED bulb with 30VTYP, 530mA LED load at 108V-132VAC/60Hz or driving a 16W analog dimmable LED bulb with 30VTYP, 530mA LED load at 108-305VAC.
The EV4031-S-00A has an excellent efficiency, can pass 3kV surge test, and meets IEC61000-3-2 Class C harmonics and EN55015 conducted EMI requirements. It has multi-protection function as over-voltage protection, over-current protection, cycle by cycle current limit, etc.
