MP4056 TRIAC Dimmable, Non-isolated Offline LED Controller with Active PFC DESCRIPTION FEATURES The MP4056 is a non-isolated, TRIAC- Adaptive Dimmer Type Detection and dimmable, offline LED controller with active Phase-Cut-Based Dimming Control PFC. It outputs an accurate LED current for an Good Dimmer Compatibility and Deep non-isolated lighting application with a single- Dimming Range stage converter. PWM Input Analog Dimming Fast Start-Up without Perceptible Delay The MP4056 implements power-factor Programmable Current Fold-back to correction and works in boundary-conduction Prolong the LED lifetime (NTC) mode to reduce MOSFET switching losses. Color Temperature and Brightness Control The adaptive dimmer type detection and phase- for Warm Sunset Dimming application cut-based dimming control achieves good Accurate Line & Load Regulation dimmer compatibility and deep dimming range. High Power Factor The MP4056 has an integrated charging circuit Operates in Boundary Conduction Mode at the supply pin for fast start-up without a Cycle-by-Cycle Current Limit perceptible delay. Over-current Protection Output Over-Voltage Protection With the unique control of DIM, the MP4056 Output Short-Circuit Protection supports color temperature and brightness ZCD Pin Short-Circuit Protection control for warm sunset dimming application. Over-Temperature Protection The MP4056 has multiple protections that Available in SOIC-8/MSOP-10/SOIC-14 greatly enhance system reliability and safety, Package including output over-voltage protection, output short-circuit protection, over-current protection, programmable thermal fold-back APPLICATIONS (MSOP10/SOIC14), ZCD pin short circuit Solid-State Lighting up to 50W protection, supply-pin under-voltage lockout, Industrial and Commercial Lighting and over-temperature protection. Residential Lighting All fault protections feature auto-restart. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance. The MP4056 is available in SOIC-8/MSOP- MPS and The Future of Analog IC Technology are Registered Trademarks 10/SOIC-14 package. of Monolithic Power Systems, Inc.
