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 over-voltage and over-current protections, short-circuit protection, and over-temperature protection.
The MP4032-2 is available in an SOIC8-7A package.
