MP4030A - Primary-Side-Control Offline LED Controller

General Description

The MP4030A is a TRIAC-dimmable, primaryside-control, offline LED lighting controller with active PFC.

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

Key Features

  • multiple protections including over-voltage protection (OVP), shortcircuit protection (SCP), primary-side overcurrent protection (OCP), supply-pin undervoltage lockout (UVLO), and over temperature protection (OTP). All of which not only simplifies circuit design but also enhances system reliability and safety greatly. All fault protections feature auto-restart. The MP4030A is available in an 8-pin SOIC package.

The Future of Analog IC Technology MP4030A TRIAC-Dimmable, Primary-Side-Control Offline LED Controller with Active PFC DESCRIPTION The MP4030A is a TRIAC-dimmable, primaryside-control, 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 realcurrent-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 MP4030A implements power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses.
