1、DESCRIPTIONThe MP4027 is a primary-side-contol, offline LED controller that achieves high-power factor and accurate LED current for isolated, singlepower-stage lighting applications in an FCTSOT package. The proprietary real-currentcontrol method accurately controls LED current from primary-side inf
2、ormation with good line and load regulation. The primary-side-control eliminates the sec on dary-side feedback compo nents and the opto-coupler to significantly simplify LED- lighting-system design.The MP4027 integrates power-factor correction and works in boundary-conduction mode to reduce MOSFET s
3、witching losses.The MP4027 has NTC function and allows PWM dimmirg.The MP4O270 multiple protect!on features greatly enhance system reliability and safety. These features include over-voltage protect!on, short-circuit protection, primary-side over- current protect!on； brown out protection, cycle by-c
