MP3383GS-Z

Overview

The MP3383GS-Z is a step-up WLED controller from Monolithic Power Systems designed for driving four LED strings. It supports a maximum output voltage of 80V and delivers up to 400mA per string. The device operates within an input voltage range of 6V to 33V at a fixed switching frequency of 500kHz. Packaged in a 16-lead SOIC, it functions reliably between -40°C and +125°C.

Feature Summary

• Supports PWM dimming for brightness control
• Includes short circuit and thermal protection mechanisms

Applications

• LCD backlighting systems
• WLED driver circuits

Procurement Notes

Verify the specific suffix 'Z' against official MPS documentation to confirm RoHS compliance status. Ensure the SOIC-16 package variant matches your PCB footprint requirements. Confirm that the 6V to 33V input range aligns with your system's power supply specifications before finalizing procurement.

Selection Notes

Select this component when designing high-voltage WLED backlights requiring four independent channels. It is suitable for applications needing 400mA current capability per string. Consider the 500kHz fixed frequency for EMI management. Verify compatibility with PWM dimming signals if variable brightness is required.
