The Future of Analog IC Technology
Offline LED Driver
with Fully-Integrated Internal MOSFET
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
