MP4008GS

Overview

The MP4008GS-Z is a high-brightness, high-current accuracy WLED boost controller from Monolithic Power Systems. It operates within a 9V to 28V input voltage range and supports both Boost and SEPIC topologies. The device features a fixed switching frequency of 180kHz and utilizes current control mode architecture. It provides a 280mV feedback voltage with ±1.8% accuracy for precise LED current regulation. The component is housed in an SOIC-8 package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Supports Boost and SEPIC topologies for flexible LED driver design
• Enables fast PWM dimming for high contrast ratio applications
• Integrates comprehensive protection mechanisms including overvoltage, overcurrent, and thermal shutdown

Applications

• High brightness white LED lighting systems
• LCD panel backlighting circuits
• General purpose DC-DC LED driver designs

Procurement Notes

Verify the specific suffix (Z or P) when ordering, as it indicates the packaging format rather than a functional change. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the selected variant matches the required reel or cut tape quantity constraints for your manufacturing line.

Selection Notes

Select this controller for applications requiring wide input voltage ranges up to 28V. The fixed 180kHz frequency allows for compact passive component selection. Consider the ±1.8% current accuracy for uniformity-sensitive displays. Evaluate the SOIC-8 package size against available PCB real estate constraints.

Part Context

This component belongs to the MP4008 series of LED lighting drivers designed by Monolithic Power Systems. It is specifically engineered for driving high-brightness LEDs in portable and general illumination devices. The series emphasizes high current accuracy and robust protection features suitable for demanding electronic environments.

Replacement Considerations

Direct substitutes include the MP4008GS-P variant, which shares identical electrical characteristics but differs in packaging configuration.
