Monolithic Power Systems EV4030-S-00A

108Vac~132Vac/60Hz, 21Vo/350mA Primary-side-control with Active PFC Off-line Dimmable LED Driver Evaluation Board


Eingangsspannung108-132 V
Ausgang 121 V / 0.35 A


The EV4030-S-00A Evaluation Board is designed to demonstrate the capabilities of MP4030. The MP4030 is a primary-side-control offline LED lighting controller which can achieve high power factor and accurate current for Triac dimmable LED lighting application. It works inboundary conduction mode for reducing the MOSFET and Diode switching losses.

The EV4030-S-00A is typically designed for driving a 7.5W Triac dimmable LED bulb with 21VTYP, 350mA LED load from 108VAC to 132VAC, 60Hz.

The EV4030-S-00A has an excellent efficiency and meets IEC61547 surge immunity, IEC61000-3-2 Class C harmonics and EN55015 conducted EMI requirements. It has multi-protection function as over-voltage protection, short-circuit protection, cycle by cycle current limit, etc.
