Product Description

The MP4032-1 is a TRIAC-dimmable, primary-side controlled, offline, LED lighting driver with an integrated 500V 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 secondary-side LED current using primary-side information. It simplifies LED lighting systems and increases efficiency by removing the secondary feedback components and the current-sensing resistor. The MP4032-1 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 over-voltage and over-current protections, short-circuit protection, and over-temperature protection. The MP4032-1 is available in an SOIC8-7A package.
