MP3302DJ-LF-P

LED Driver IC Overview

The MP3302DJ-LF-P is a boost converter IC designed for driving white LED arrays from a single lithium-ion battery. 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. It utilizes a TSOT-23-5 surface-mount package and functions across a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates internal power MOSFET capable of driving multiple series-connected white LEDs
• Supports single-wire dimming control for brightness adjustment
• Includes comprehensive protection mechanisms such as overvoltage, undervoltage lockout, and thermal shutdown

LED Driver IC Applications

• Portable electronic devices requiring WLED backlighting
• Single-cell lithium-ion battery powered systems
• Compact LED lighting modules

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging when ordering. Confirm that the TSOT-23-5 package variant matches your PCB footprint requirements. Ensure design compatibility with the 1.3 MHz switching frequency regarding external component selection. Validate that the operating temperature range meets your application's environmental specifications.

LED Driver IC Selection Notes

Select this component for applications requiring high efficiency in space-constrained designs. The low feedback voltage minimizes power loss compared to standard drivers. Consider the internal MOSFET current limit when sizing the LED string. Evaluate the single-wire control interface if dimming functionality is required without additional GPIO pins.

LED Driver IC Part Context

This part belongs to the MP3302 family of WLED drivers from Monolithic Power Systems. It shares core architecture with variants like the MP3302DD-LF-Z but differs in packaging. The DJ suffix typically denotes the TSOT-23-5 package, distinguishing it from QFN options in the same series.

LED Driver IC Replacement Considerations

Direct substitutes include MP3302DJ-LF-Z which shares identical electrical characteristics but may differ in reel packaging quantity. Verify pin-to-pin compatibility before replacing MP3302DD-LF-P variants, noting the package difference between TSOT-23-5 and QFN-8.
