MP3385BGR-P

Overview

The MP3385BGR-P is a WLED controller IC featuring a buck topology with an input voltage range of 4.5 V to 33 V and a maximum output voltage of 80 V per string. It supports four LED strings with a maximum current of 300 mA per channel. The device operates at switching frequencies between 100 kHz and 900 kHz within a -40°C to +125°C temperature range. It utilizes a QFN-20 package for surface mount installation.

Feature Summary

Integrates an I2C digital interface for flexible configuration of operation modes, protection settings, and dimming parameters.
Supports PWM dimming functionality to adjust brightness levels efficiently.
Provides precise current regulation with specified accuracy for consistent LED performance.

Applications

LCD panel backlighting systems
White LED lighting drivers
Portable electronic devices requiring high-brightness illumination

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the QFN-20 thermal pad requirements for adequate heat dissipation during operation.

Selection Notes

Select this component for designs requiring independent control of multiple white LED strings via digital interface. Consider the 80V output limit and 300mA current capability against load requirements. Evaluate the 4.5V to 33V input range suitability for system power architectures.

Part Context

Part of the MP3385 series from Monolithic Power Systems, designed specifically for driving white LEDs in display applications. The series offers various configurations including different channel counts and package options to suit diverse board space and performance needs.
