MP4032-2 Offline LED Driver with Fully-Integrated Internal MOSFET The Future of Analog IC Technology DESCRIPTION FEATURES The MP4032-2 is a TRIAC-dimmable, offline LED lighting driver with an integrated 600V MOSFET. It can achieve a high power factor and accurate LED current control for lighting applications in a single-stage converter. The proprietary real-current control can accurately control the LED current.  The MP4032-2 has a power-factor-correction function and works in boundary-conduction mode that reduces power losses. The DRAIN pin can supply current to the internal charging circuit for start-up without a perceptible delay. The proprietary dimming control extends the TRIAC-based dimming range. The multiple protections greatly enhance system reliability and safety. These protections include VCC under-voltage lockout, LED overvoltage and over-current protections, shortcircuit protection, and over-temperature protection. The MP4032-2 is available in an SOIC8-7A package.            Internal MOSFET with 600V High Voltage Rating Internal Charging Circuit for Fast Start-Up Accurate Line Regulation Flicker-Free, Phase-Controlled TRIAC Dimming with Extended Dimming Range High Power Factor Boundary-Conduction Mode VCC UVLO Cycle-by-Cycle Current Limiting Over-Voltage Protection Short-Circuit Protection Over-Temperature Protection Available in SOIC8-7A Package APPLICATIONS    Solid-State Lighting Industrial and Commercial Lighting Residential Lighting All MPS parts are lead-free and adhere to the RoHS directive.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD(MAX)=(TJ(MAX)TA)/ θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 4) The device is not guaranteed to function outside of its operation conditions. 5) Measured on JESD51-7 4-layer board.
