MP3302DJ-LF-Z

LED Driver IC Overview

The MP3302DJ-LF-Z is a boost converter IC designed for driving white LED arrays from a single lithium-ion cell. It operates within an input voltage range of 2.5 V to 6 V and delivers up to 1.3 A output current. The device features a fixed switching frequency of 1.3 MHz and supports output voltages from 2.5 V to 36 V. Packaged in a TSOT-23-5 format, it includes internal power MOSFETs and offers protection against overvoltage, overcurrent, and thermal overload.

LED Driver IC Feature Summary

• Integrates internal power MOSFETs capable of driving multiple series-connected white LEDs
• Supports single-wire dimming control for simplified interface requirements
• Includes comprehensive protection mechanisms such as load open-circuit shutdown and thermal overload protection

LED Driver IC Applications

• Backlighting for mobile devices
• White LED driver circuits
• Portable electronic lighting systems

LED Driver IC Procurement Notes

Verify the specific suffix 'DJ' corresponds to the TSOT-23-5 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design parameters align with the specified 2.5 V to 6 V input range and 1.3 A current limits to maintain operational integrity.

LED Driver IC Selection Notes

Select this component for applications requiring a compact solution for single-cell lithium-ion powered LED backlighting. The high switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the TSOT-23-5 package constraints for thermal management and PCB layout space availability.

LED Driver IC Part Context

This part belongs to the MP3302 series of LED lighting drivers manufactured by Monolithic Power Systems. It is specifically engineered for portable electronics where space efficiency and battery life are critical. The series utilizes a fixed-frequency current mode control architecture to regulate LED brightness efficiently.

LED Driver IC Replacement Considerations

Check MPS datasheets for alternative packages like QFN-8 if pinout compatibility is not required. Verify electrical specifications against other WLED drivers in the portfolio for direct pin-to-pin substitution needs.
