The Future of Analog IC Technology
MP4031
TRIAC and Analog Dimmable,
Primary-Side–Controlled
Offline LED Controller with Active PFC
DESCRIPTION
The MP4031 is a TRIAC and analog dimmable,
primary-side–controlled, offline LED lighting
controller with active PFC. It can output an
accurate LED current for an isolated lighting
application with a single-stage converter. The
proprietary real-current–control method can
accurately control the LED current using primary-
side information. It can significantly simplify LED
lighting system design by eliminating secondary-
side feedback components and the optocoupler.
The MP4031 implements power-factor correction
and works in boundary-conduction mode to
reduce MOSFET switching losses.
The MP4031 has an integrated charging circuit at
the supply pin for fast start-up without a
perceptible delay.
The proprietary dimming control expands the
TRIAC-based dimming range.
The special current sense structure can
implement analog dimming.
The MP4031 has multiple protections that greatly
enhance system reliability and safety, including
over-voltage protection, overload protection,
supply-pin under-voltage lockout, and over-
temperature protection.
All fault protections feature auto-restart.
The MP4031 is available in an 8-pin SOIC
package.
