NON-ISOLATED TRIAC DIMMABLE LED DRIVER S

The MP4068 is a highly integrated TRIAC dimmable LED driver with a high power factor (PF). It precisely can output regulates precisely an accurate LED current for ain non-isolated lighting applications., Onlywith a single winding inductor is required to realize the solution. For low-line (120VAC) applications, The integrated 500V MOSFET can make sure ensures that the system canto withstand a pass 500V surge test without MOV or TVS for low line input application. It features proprietary hybrid operation mode, which is designed to to get a achieve good dimming performance. The MP4068 is specifically designed specifically for low- line input (120VAC), and TRIAC -dimmable LED lighting applications, especially for the low cost and small form factor applications.The accurate output LED current is achieved by an internal averaging current feedback loop. An internal high- voltage regulator makes the MP4068 start-up quickly without a perceptible delay. The power de-rating at high temperature makes the system flicker-free when the ambient temperature is high.The MP4068 has features various protection featuress like such as VCC Under- Voltage Lockout (UVLO), Over- Voltage Protection (OVP), and Short- Circuit Protection (SCP). All of these features make MP4068 an ideal solution for simple, off-line, and non-isolated TRIAC dimmable LED lighting applications.
