MP4033 - Primary Side Control Offline LED Controller

General Description

The MP4033 is a TRIAC-dimmable primaryside

control, offline LED lighting controller with active PFC.

It is also available for applications that requires analog dimming with PWM input.

It outputs an accurate LED current for an isolated lighting application with a single-stage converter.

Key Features

  • Primary-Side-Control without Requiring a Secondary-Side Feedback Circuit.
  • Adaptive Dimmer Type Detection and Phase-Cut-Based Dimming Control.
  • Good Dimmer Compatibility and Deep Dimming Range.
  • Analog Dimming with PWM Input.
  • Fast Start-Up without Perceptible Delay.
  • Programmable Current Fold-back to Prolong the LED lifetime (NTC).
  • Color Temperature and Brightness Control for Warm Sunset Dimming.

The Future of Analog IC Technology MP4033 TRIAC Dimmable, Primary Side Control Offline LED Controller with Active PFC DESCRIPTION The MP4033 is a TRIAC-dimmable primaryside–control, offline LED lighting controller with active PFC. It is also available for applications that requires analog dimming with PWM input. It outputs an accurate LED current for an isolated lighting application with a single-stage converter. The proprietary real-current–control method accurately controls the LED current using primary-side information. The MP4033 implements power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses. The adaptive dimmer type detection and phasecut-based dimming control achieves good dimmer compatibility and deep dimming range.
