MP4030A TRIAC-Dimmable, Primary-Side-Control Offline LED Controller with Active PFC The Future of Analog IC Technology FEATURES DESCRIPTION Primary-Side-Control without Requiring a The MP4030A is a TRIAC-dimmable, primary- Secondary-Side Feedback Circuit side-control, offline LED lighting controller with Internal Charging Circuit at the Supply Pin for active PFC. It can output an accurate LED Fast Start-Up current for an isolated lighting application with a Accurate Line & Load Regulation single-stage converter. The proprietary real- High Power Factor and Improved THD current-control method can accurately control the Flicker-Free, Phase-Controlled TRIAC LED current using primary-side information. It Dimming with Expanded Dimming Range 1% can significantly simplify LED lighting system to 100% Full Range design by eliminating secondary-side feedback Operates in Boundary Conduction Mode components and the optocoupler. Cycle-by-Cycle Current Limit The MP4030A implements power-factor Primary-Side, Over-Current Protection correction and works in boundary-conduction Over-Voltage Protection mode to reduce MOSFET switching losses. Short-Circuit Protection The MP4030A has an integrated charging circuit Over-Temperature Protection at the supply pin for fast start-up without a Available in an 8-Pin SOIC Package perceptible delay. APPLICATIONS The proprietary dimming control expands the Solid-State Lighting, including: TRIAC-based dimming range. Industrial and Commercial Lighting The MP4030A features multiple protections Residential Lighting including over-voltage protection (OVP), short- All MPS parts are lead-free and adhere to the RoHS directive.
