DESCRIPTION

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.
