MP4012DS - High-Current Accuracy WLED Controller

Download the MP4012DS datasheet PDF. This datasheet also covers the MP4012 variant, as both devices belong to the same high-current accuracy wled controller family and are provided as variant models within a single manufacturer datasheet.

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.

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.

The Future of Analog IC Technology MP4012 High-Brightness, High-Current Accuracy WLED Controller 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. Its feedback voltage can be adjusted by the external DC bias voltage. The MP4012 can work in constant frequency operation mode or constant off time mode. It features programmable slop compensation that can optimize the control loop regulation and avoid sub harmonic oscillation.
