The EV4088-N-00A Evaluation Board is designed to demonstrate the capabilities of MP4088. The MP4088 is a highly integrated TRIAC dimmable LED driver with high power factor. It is specifically designed for high-line input (230VAC), no-isolated, TRIAC-dimmable LED lighting applications, especially for the low cost and small form factor applications.
The MP4088 integrates a 500V MOSFET. Only a single winding inductor is required to realize the solution. It features MPS’s proprietary hybrid operation mode which is designed to achieve good dimming performance.
The EV4088-N-00A is typically designed for driving an 8.1W TRIAC dimmable LED bulb with 60VTYP, 135mA LED load from 198VAC to 265VAC, 50Hz.
The EV4088-N-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; output short-circuit protection, thermal shut down, etc.

The MP4088 is a highly integrated, TRIAC dimmable LED driver with an integrated 500V MOSFET that regulates precise LED currents in non-isolated lighting applications and requires only a single winding inductor. The MP4088 features MPS proprietary hybrid operation mode, which is designed to achieve optimal dimming performance. The MP4088 is designed specifically for high-line input (230VAC) and TRIAC dimmable LED lighting applications, especially for low-cost and small form-factor applications. The accurate output LED current is achieved by an internal averaging current feedback loop. An internal high-voltage regulator makes the MP4088 start up quickly without a perceptible delay. The power de-rating at high temperatures makes the system flicker-free when the ambient temperature is high. Full protections features include VCC under-voltage lockout (UVLO), over-voltage protection (OVP), and short-circuit protection (SCP). All of these features make the MP4088 an ideal solution for simple, offline, and non-isolated TRIAC dimmable LED lighting applications. The MP4088 is available in TSOT23-5, SOIC8-7A, and SOIC-8 EP packages.
