MP3398AGF-P

Overview

The MP3398AGF-P is a four-channel boost white LED controller manufactured by Monolithic Power Systems. 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 TSSOP-EP-16 package and supports switching frequencies between 150 kHz and 621 kHz. It features open-drain outputs and handles power dissipation up to 2.78 W. The component functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Supports independent analog dimming (ADIM) and PWM dimming for flexible brightness control
• Includes inductor short protection and comprehensive fault management mechanisms
• Enables cascading multiple units via shared power supply architecture

Applications

• TV backlight systems
• Monitor display panels
• Large LCD panel backlighting

Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets. Check humidity sensitivity classification before storage. Validate lead-free solderability requirements against assembly specifications.

Selection Notes

Select this model when four independent current channels are required for uniform LED string balancing. Ensure the application demands peak current mode control with adjustable frequency. Verify that the system input voltage remains within the specified 5 V to 28 V operational window.

Part Context

This component belongs to the MP3398A series of WLED controllers designed for high-performance display applications. It integrates internal current sources to maintain precise current matching across strings. The device drives external MOSFETs to regulate boost converter operation efficiently.

Replacement Considerations

MP3398AGF-Z serves as a direct alternative with identical electrical characteristics but different packaging format.
