LED Driver IC Procurement Notes

Verify the specific suffix 'GQ-P' against official Monolithic Power Systems documentation to confirm package type and lead-free status. Ensure the design accommodates the specified operating temperature range and input voltage limits. Cross-reference the datasheet for thermal dissipation requirements associated with the QFN-10 package under intended load conditions.

LED Driver IC Selection Notes

Select this component when a single-channel boost driver is required for white LED strings. It is suitable for designs needing a wide input voltage range up to 25 V. Consider the 1.3 A current limit and 1 MHz switching frequency for inductor selection. Verify that the QFN-10 footprint matches the PCB layout constraints.

LED Driver IC Part Context

This part belongs to the MP3310 series of LED drivers from Monolithic Power Systems. The series includes variants such as MP3310N and MP3310EQ-LF-P, which share similar functional characteristics but may differ in temperature ratings or packaging options. The MP3310NGQ-P specifically denotes the industrial temperature grade and QFN-10 package configuration.

LED Driver IC Replacement Considerations

The MP3310EQ-LF-P is a documented variant within the same family, offering similar functionality with potentially different commercial temperature ratings. Verify pin compatibility and electrical specifications before substitution.
