MP3398HGS-Z

Overview

The MP3398HGS-Z is a Monolithic Power Systems LED lighting driver IC featuring a boost topology and four output channels. It operates within an input voltage range of 4.5 V to 33 V, supporting a maximum output voltage of 80 V. The device accommodates up to 400 mA per string and utilizes direct pulse width modulation for dimming control. Designed for surface-mount installation in SOIC-16 packages, it functions reliably across temperatures from -40°C to +125°C with a power dissipation rating of 1.56 W.

Feature Summary

• Supports four independent LED strings with open-drain outputs
• Enables direct pulse width modulation for precise brightness control
• Integrates high-voltage return capability for flexible circuit design

Applications

• White LED controller circuits
• LED lighting driver systems
• Step-up WLED controller designs

Procurement Notes

Verify the specific suffix Z against official manufacturer documentation to confirm package and tape specifications. Confirm RoHS compliance status through current datasheets. Ensure the selected distributor provides valid traceability for the SOIC-16 component. Cross-reference the part number with the latest MPS release notes to validate operational parameters before integration.

Selection Notes

Select this component when designing boost converters requiring four-channel LED drive capabilities. Consider the 80 V output limit and 400 mA per-string capacity for appropriate load matching. Evaluate the SOIC-16 footprint against available board space. Verify that the 4.5 V to 33 V input range aligns with the system power supply architecture.

Part Context

This part belongs to the MP3398H series of LED drivers from Monolithic Power Systems. It shares the core boost architecture with variants like the MP3398HGS-P but differs in packaging and reel specifications. The H-series designation indicates specific electrical characteristics tailored for high-voltage return applications compared to other family members.

Replacement Considerations

The MP3398HGS-P is a documented substitute within the same series. Verify pin compatibility and electrical parameter alignment before substitution.
