MP3388DR-LF-Z

Overview

The MP3388DR-LF-Z is an 8-channel white LED driver IC from Monolithic Power Systems, utilizing a boost topology. It operates on a supply voltage range of 4.5 V to 25 V and supports output voltages up to 50 V. The device functions at a switching frequency of 1.25 MHz and is housed in a QFN-24 package. It is rated for temperatures between -40°C and +85°C. This component is classified as Not Recommended for New Designs (NRND).

Feature Summary

Provides eight independent output channels for driving white LEDs.
Integrates a high-efficiency DC-DC boost converter for backlight applications.

Applications

Backlight LED driving for mobile devices
White LED illumination systems

Procurement Notes

Verify the current lifecycle status before procurement, as this part is designated as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options meet project requirements. Ensure compatibility with the QFN-24 footprint and validate thermal performance within the specified operating temperature range of -40°C to +85°C during integration.

Selection Notes

Select this component only if legacy design continuity is required, given its NRND status. Evaluate the 8-channel configuration against system complexity needs. Consider the 1.25 MHz switching frequency for EMI management and the 50 V maximum output capability for series LED string configurations. Verify availability through authorized distributors for remaining stock.

Part Context

This IC belongs to the MP3388 series of LED lighting drivers manufactured by Monolithic Power Systems. It is designed specifically for multi-channel white LED applications, offering integrated power regulation and control features suitable for portable electronics requiring uniform backlighting across multiple diodes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on channel count, boost topology, and package compatibility.
