MP4068 Non-Isolated,TRIAC Dimmable PFC LED Driver for 120VAC, Up to 10W LEDs The Future of Analog IC Technology DESCRIPTION FEATURES The MP4068 is a highly integrated TRIAC Excellent TRIAC Dimming Performance dimmable LED driver with a high power factor Lowest Cost BOM (PF). It regulates precisely LED current in non- Constant Current LED Driver isolated lighting applications. Only a single Integrated 500V MOSFET winding inductor is required to realize the Internal HV Fast Start-Up solution. For low-line (120VAC) applications, Single Winding Inductor the integrated 500V MOSFET ensures that the High Power Factor(>0.7) system can withstand a 500V surge test without Good LED Current Accuracy MOV or TVS. It features MPS proprietary Supports Buck/Buck-Boost Topology hybrid operation mode, which is designed to LED Current Foldback at High Temperature achieve good dimming performance. The Thermal Shutdown (Auto Re-Start with MP4068 is designed specifically for low-line Hysteresis) input (120VAC) and TRIAC dimmable LED VCC Under-Voltage Lockout with Hysteresis lighting applications, especially for low cost and (UVLO) small form factor applications. Programmable Over-Voltage Protection The accurate output LED current is achieved by Output Short-Circuit Protection an internal averaging current feedback loop. An Available in SOIC8-7A/SOIC-8 EP internal high-voltage regulator makes the Packages MP4068 start-up quickly without a perceptible delay. The power de-rating at high temperature APPLICATIONS makes the system flicker-free when the ambient 120VAC, Up to 10W LED Lighting temperature is high. Residential and Commercial Lighting The MP4068 has protection features such as TRIAC Dimmible LED Lighting, A19, GU10, VCC under-voltage lockout (UVLO), over- PAR Lamps voltage protection (OVP), and short-circuit All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For protection (SCP). All of these features make MPS green status, please visit MPS website under Quality Assurance. MP4068 an ideal solution for simple, off-line, MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. and non-isolated TRIAC dimmable LED lighting applications. The MP4068 is available in SOIC8-7A and SOIC-8 EP packages. MP4068 Rev. 1.01 www.MonolithicPower.com 1 7/30/2015 MPS Proprietary Information. Patent Protected.
