Product Description

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, tThe 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. The It features MPS’s 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 UnderuUnder- vVoltage lLockout (UVLO), oOver- vVoltage pProtection (OVP), and sShort- cCircuit pProtection (SCP). All of these features make MP4068 an ideal solution for simple, off-line, and non-isolated TRIAC dimmable LED lighting applications. The MP4068 is available inn the TSOT23-5 and SOIC8-7A and SOIC-8 -EP packages.
