MP4033 TRIAC Dimmable, Primary Side Control Offline LED Controller with Active PFC The Future of Analog IC Technology DESCRIPTION FEATURES The MP4033 is a TRIAC-dimmable primary- Primary-Side-Control without Requiring a sidecontrol, offline LED lighting controller with Secondary-Side Feedback Circuit active PFC. It is also available for applications Adaptive Dimmer Type Detection and that requires analog dimming with PWM input. It Phase-Cut-Based Dimming Control outputs an accurate LED current for an isolated Good Dimmer Compatibility and Deep lighting application with a single-stage converter. Dimming Range The proprietary real-currentcontrol method Analog Dimming with PWM Input accurately controls the LED current using Fast Start-Up without Perceptible Delay primary-side information. Programmable Current Fold-back to Prolong the LED lifetime (NTC) The MP4033 implements power-factor Color Temperature and Brightness Control correction and works in boundary-conduction for Warm Sunset Dimming application mode to reduce MOSFET switching losses. Accurate Line & Load Regulation The adaptive dimmer type detection and phase- High Power Factor cut-based dimming control achieves good Operates in Boundary Conduction Mode dimmer compatibility and deep dimming range. Cycle-by-Cycle Current Limit The MP4033 has an integrated charging circuit Winding Short Circuit Protection at the supply pin for fast start-up without a Output Over-Voltage Protection perceptible delay. Output Short-Circuit Protection With the unique control of the driver pin DIM, ZCD Pin Short-Circuit Protection the MP4033 supports color temperature and Over-Temperature Protection brightness control for warm sunset dimming Available in SOIC-8/MSOP-10/SOIC-14 application Package The MP4033 has multiple protections that APPLICATIONS greatly enhance system reliability and safety, Solid-State Lighting up to 50W including output over-voltage protection, output Industrial and Commercial Lighting short-circuit protection, winding short circuit Residential Lighting protection, programmable thermal fold-back (MSOP10/SOIC14), ZCD pin short circuit All MPS parts are lead-free and adhere to the RoHS directive.
