MP3306EG-LF-Z

LED Driver IC Overview

The MP3306EG-LF-Z is a monolithic LED lighting driver IC designed for white LED (WLED) applications. It integrates a synchronous boost converter topology with an internal disconnect field-effect transistor (FET). The device operates within a supply voltage range of 3 V to 12 V and supports a maximum output voltage of 30 V. It delivers an output current capability of 1.8 A at a typical switching frequency of 690 kHz. The component is housed in a QFN-12 package and functions reliably across an operating temperature range from -40 °C to +125 °C.

LED Driver IC Feature Summary

LED Driver IC Procurement Notes

Verify the specific suffix 'LF-Z' against the manufacturer's datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the QFN-12 footprint matches your PCB layout requirements. Confirm that the input voltage range of 3 V to 12 V aligns with your system power supply specifications before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing WLED drivers requiring high efficiency and integrated protection features. The internal disconnect FET reduces external component count compared to discrete solutions. Consider the 690 kHz switching frequency for balancing electromagnetic interference (EMI) performance against passive component size constraints in space-constrained mobile or portable devices.

LED Driver IC Part Context

This part belongs to the MP3306 series from Monolithic Power Systems, specialized for LED illumination. It differs from general-purpose buck converters by its specific boost topology and integration of the switch element. The series targets applications needing precise current regulation for LED strings without requiring complex external gate drive circuits.

LED Driver IC Replacement Considerations
