MP3021DQ-LF-P

LED Driver IC Overview

The MP3021DQ-LF-P is a white LED backlight driver IC manufactured by Monolithic Power Systems. It utilizes a charge pump topology with four output channels, each capable of delivering 30mA. The device operates within an input voltage range of 2.7V to 5.5V at a switching frequency of 1.25MHz. It is housed in a QFN-16 package and functions as a DC-DC regulator for LED applications.

LED Driver IC Feature Summary

• Integrates four independent output channels for multi-string LED driving
• Employs switched capacitor charge pump topology for efficient voltage regulation
• Features internal switches to minimize external component count

LED Driver IC Applications

• White LED backlight drivers for portable devices
• Multi-string LED lighting systems
• DC-DC regulation for low-voltage LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging details, as datasheets may reference 'Z'. Confirm current status, as related variants are often marked NRND. Ensure compatibility with required thermal management for the QFN-16 package during integration.

LED Driver IC Selection Notes

Select this component for designs requiring four isolated LED strings from a single supply. The 1.25MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 30mA per channel limit meets the target LED brightness requirements without exceeding thermal constraints.

LED Driver IC Part Context

This part belongs to the MP3021 series of LED lighting drivers. It is functionally similar to the MP3021DQ-LF-Z but differs in packaging configuration. Both share the same core charge pump architecture and electrical specifications for driving white LEDs in portable electronics.

LED Driver IC Replacement Considerations

MP3021DQ-LF-Z is a documented variant with identical electrical performance but different packaging. Verify pinout compatibility before substitution.
