MP4026GJ-Z Electronic Integrated Circuits LED Lighting Driver Offline PSR LED Controller
The Future of Analog IC TechnologyDESCRIPTION The MP4026 is a primary-side-control, offline LED controller that achieves high-power factor and accurate LED current for isolated, single-power-stage lighting applications in a tiny TSOT23-6 package. It is the next generation of the successful MP4021A. The proprietary real-current-control method accurately controls LED current from primary-side information with good line and load regulation. The primary-side-control eliminates the secondary-side feedback components and the opto-coupler to significantly simplify LED-lighting-system design. The MP4026 integrates power-factor correction and works in valley switching mode to reduce MOSFET switching losses. The MP4026’s multiple protection features greatly enhance system reliability and safety. These features include over-voltage protection, short-circuit protection, primary-side over-current protection, brown out protection, cycle-by-cycle current limiting, VCC under-voltage lockout, and auto-restart over-temperature protection. FEATURES• Real-Current Control without Secondary-Feedback Circuit • Good Line/Load Regulation • High Power Factor (≥0.9) over Universal Input Voltage • Valley Switching Mode for Improved Efficiency • Brown-Out Protection • Over-Voltage Protection • Short-Circuit Protection • Over-Temperature Protection • Primary-Side Over-Current Protection • Cycle-by-Cycle Current Limit • Input UVLO • Available in TSOT23-6 APPLICATIONS • Industrial and Commercial Lighting • Residential Lighting
