MP3398BGF

Overview

The MP3398BGF-Z is a four-channel boost white LED controller from Monolithic Power Systems, designed for high-efficiency lighting applications. It operates within an input voltage range of 5 V to 28 V and supports a fixed switching frequency of 540 kHz. Each channel delivers up to 350 mA, with a maximum power dissipation of 2.78 W. The device features PWM dimming control and functions as an overcurrent protection latch-off variant of the MP3398A. It is housed in a TSSOP-EP-16 package and operates reliably between -40°C and +125°C.

Feature Summary

Four independent output channels providing precise current regulation for white LEDs
Integrated overcurrent protection mechanism that latches off upon fault detection
Supports pulse-width modulation dimming for brightness control

Applications

White LED backlighting systems
General solid-state lighting fixtures
Portable electronic display illumination

Procurement Notes

Verify the specific suffix against official datasheets to confirm functional differences, such as the overcurrent protection behavior relative to other variants. Ensure compatibility with required thermal management solutions given the specified power dissipation limits. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during manufacturing processes.

Selection Notes

Select this component when a dedicated four-channel boost topology is required for uniform LED string driving. Consider the fixed 540 kHz frequency for electromagnetic interference filtering requirements. Evaluate the TSSOP-EP-16 package for thermal performance needs compared to alternative packages like SOIC-16 found in related series models.

Part Context

This part belongs to the MP3398B series, which serves as a specialized variant within the broader MP3398 family. It differs from standard versions by implementing a latch-off overcurrent protection scheme rather than hiccup mode. This distinction makes it suitable for applications requiring immediate shutdown on fault conditions to protect downstream components.
