📥 Download Datasheet

General Description

The MP4027 is a primary-side-control, offline LED lighting controller.

In a tiny TSOT23-8 package, it achieves high power factor (PF) and accurate LED current for isolated, single-powerstage lighting applications.

This simplifies LED-lighting-system design significantly by eliminating the secondary-side feedback components and the optocoupler.

Overview

The Future of Analog IC Technology MP4027 Primary-Side Control, Offline LED Controller with Active PFC, NTC and PWM.

Key Features

  • including over-voltage protection (OVP), short-circuit protection (SCP), primary-side over-current protection (OCP), brown-out protection, over-temperature protection (OTP), cycle-by-cycle current limit, VCC under-voltage lockout (UVLO), and autorestart function.
