MP3398AGS-P

Overview

The MP3398AGS-P is a four-channel boost white LED controller from Monolithic Power Systems, designed for TV and monitor backlight applications. It operates within an input voltage range of 5 V to 28 V and delivers up to 350 mA per channel. The device utilizes a SOIC-16 package and supports a switching frequency between 150 kHz and 621 kHz. Key electrical specifications include a maximum power dissipation of 1.56 W and operation across a temperature range of -40°C to +125°C.

Feature Summary

Integrates inductor short protection circuitry to enhance system reliability during fault conditions.
Supports independent analog and PWM dimming inputs for flexible brightness control strategies.
Provides open LED protection to detect and manage string disconnection events.

Applications

TV backlight systems
Monitor display panels

Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging configuration distinct from other variants. Confirm that the selected component matches the required thermal performance for the target application environment. Ensure compatibility with the intended PCB footprint and soldering profile for the SOIC-16 package before finalizing procurement orders.

Selection Notes

Select this model when inductor short protection is a critical design requirement for the backlight driver topology. Consider the fixed 350 mA output current capability and the wide input voltage range suitable for various power supply architectures. Evaluate the SOIC-16 package constraints against available board space and thermal management requirements.

Part Context

This component belongs to the MP3398A series of four-channel boost controllers engineered for high-performance white LED driving. The series offers scalable solutions for large LCD panel backlights by allowing multiple ICs to share a single power source. It features peak current mode control and precise current matching between channels to ensure uniform illumination across the display area.
