EV4031-S-00A 108Vac~305Vac, 30V/530mA Primary-side-control with Active PFC TRIAC and Analog Dimmable LED Driver EVB The Future of Analog IC Technology DESCRIPTION FEATURES The EV4031-S-00A Evaluation Board is Fast Start up designed to demonstrate the capabilities of Triac Dimmable, with 1% to 100% dimming MP4031. The MP4031 is a primary-side-control range and the dimming curve meets offline LED lighting controller which can achieve standard SSL6 high power factor and accurate current for Analog-Dimmable either Triac dimmable or analog dimmable LED Real current control without secondary- lighting application. It works in boundary feedback circuit conduction mode for reducing the MOSFET and Unique architecture for superior line Diode switching losses. regulation High power factor>0.9 over 108Vac to The EV4031-S-00A is typically designed for 305Vac either driving a 16W Triac dimmable LED bulb Boundary conduction mode improves with 30V , 530mA LED load at 108V- TYP efficiency 132VAC/60Hz or driving a 16W analog dimmable LED bulb with 30V , 530mA LED Input UVLO TYP load at 108-305VAC. Cycle-by-cycle current limit Over-voltage protection (OVP) The EV4031-S-00A has an excellent efficiency, Over-current protection (OCP) can pass 3kV surge test, and meets IEC61000- Over-temperature protection (OTP) 3-2 Class C harmonics and EN55015 Fit inside PAR38 bulb enclosure conducted EMI requirements. It has multi- protection function as over-voltage protection, APPLICATIONS over-current protection, cycle by cycle current Solid State Lighting limit, etc. Industrial & Commercial Lighting ELECTRICAL SPECIFICATION Residential Lighting Parameter Symbol Value Units All MPS parts are lead-free and adhere to the RoHS directive.
