MP4012DS Datasheet High-current ACcuracy Wled Controller

Manufacturer: Monolithic Power Systems

Overview: The Future of Analog IC Technology MP4012 High-Brightness, High-Current Accuracy WLED.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP4012 is a current mode controller designed for driving the high brightness Light Emitting Diodes (LEDs) from extremely wide input voltage 8V~55V.

It can be used in Boost, Buck, Buck-boost and SEPIC topologies.

The MP4012 drives external MOSFET with fixed frequency/constant off-time architecture to regulate the LED current, which is measured through an external current sense resistor.

Key Features

  • programmable slop compensation that can optimize the control loop regulation and avoid sub harmonic oscillation. The MP4012 implements high frequency PWM Dimming with external disconnect MOSFET. It achieves analog dimming by adjusting the feedback voltage. The MP4012 has synchronizing function, which makes multiple ICs synchronized to each other by connecting SYNC pins together. The MP4012 includes under-voltage lockout, over voltage protection, open and short hiccup mode protection, overload pr.
