MP3394SGY

Overview

The MP3394SGY is a Monolithic Power Systems LED lighting driver IC featuring four output channels with a boost topology. It operates within an input voltage range of 5 V to 28 V and supports a fixed switching frequency of 570 kHz. The device provides an output current of 180 mA per channel and dissipates up to 1.74 W of power. It is housed in a SOIC-20 package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

Integrates four internal current sources for precise white LED driving
Supports PWM dimming control via external signals
Includes open LED protection mechanisms for circuit safety

Applications

White LED backlighting for 2D monitors
White LED backlighting for 3D monitors
White LED backlighting for televisions

Procurement Notes

Verify component authenticity through authorized MPS distributors or verified supply chain partners. Confirm the specific suffix matches the required package and thermal specifications. Check RoHS compliance status against current environmental regulations. Ensure storage conditions respect humidity sensitivity levels to prevent moisture damage prior to soldering.

Selection Notes

Select this model when designing systems requiring four independent LED channels with a fixed 570 kHz switching frequency. It is suitable for applications needing 180 mA per channel output within a 5 V to 28 V input range. Consider the SOIC-20 package constraints for PCB layout. Evaluate thermal dissipation requirements given the 1.74 W power rating.

Part Context

This component belongs to the MP3394S series, designed specifically for driving white LED arrays in display backlights. The series utilizes a boost converter architecture to step up lower input voltages to drive multiple LED strings in series. It is engineered for high efficiency and precise current matching across all channels.
