MP4088 Non-Isolated, High PFC, TRIAC Dimmable LED Driver for 230VAC, Up to 10W LEDs The Future of Analog IC Technology DESCRIPTION FEATURES Excellent TRIAC Dimming Performance The MP4088 is a highly integrated, TRIAC Lowest BOM Cost dimmable LED driver with an integrated 500V MOSFET that regulates precise LED currents in Constant Current LED Driver non-isolated lighting applications and requires Integrated 500V MOSFET only a single winding inductor. The MP4088 Internal HV Fast Start-Up features MPS proprietary hybrid operation Single Winding Inductor mode, which is designed to achieve optimal High Power Factor (>0.7) dimming performance. The MP4088 is Good LED Current Accuracy designed specifically for high-line input Supports Buck and Buck-Boost Topology (230VAC) and TRIAC dimmable LED lighting LED Current Foldback at High Temperature applications, especially for low-cost and small Thermal Shutdown (Auto-Restart with form-factor applications. Hysteresis) The accurate output LED current is achieved by VCC Under-Voltage Lockout with Hysteresis an internal averaging current feedback loop. An (UVLO) internal high-voltage regulator makes the Programmable Over-Voltage Protection MP4088 start up quickly without a perceptible (OVP) delay. The power de-rating at high Output Short-Circuit Protection (SCP) temperatures makes the system flicker-free Auto-Restart Function when the ambient temperature is high. Available in TSOT23-5, SOIC8-7A, and SOIC-8 EP Packages Full protections features include VCC under- voltage lockout (UVLO), over-voltage protection APPLICATIONS (OVP), and short-circuit protection (SCP). All of 230VAC, Up to 10W LED Lighting these features make the MP4088 an ideal Residential and Commercial Lighting solution for simple, offline, and non-isolated TRIAC Dimmable LED Lighting, A19, GU10, TRIAC dimmable LED lighting applications. PAR Lamps The MP4088 is available in TSOT23-5, SOIC8- All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For 7A, and SOIC-8 EP packages.
