MP3412EJ-LF-Z

Overview

The MP3412EJ-LF-Z is a synchronous boost WLED driver manufactured by Monolithic Power Systems. It operates with an input voltage range of 800 mV to 4.4 V and delivers an output current of 1.1 A. The device features a fixed switching frequency of 1.05 MHz and supports PWM dimming for backlight applications. It provides an adjustable output voltage between 2.5 V and 5 V. The component functions within a junction temperature range of -40°C to +125°C and is housed in a TSOT-23-6 package.

Feature Summary

Integrates synchronous rectification to enhance conversion efficiency and eliminate the need for external Schottky diodes.
Supports PWM dimming control for precise backlight brightness regulation in display systems.
Features low startup voltage capability to maximize battery life in portable devices.

Applications

Backlight drivers for mobile phone displays
Backlight drivers for tablet computer screens
Power management for portable electronic devices

Procurement Notes

Verify the specific suffix 'LF-Z' against official Monolithic Power Systems documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with the required TSOT-23-6 footprint and pinout during PCB layout. Cross-reference environmental compliance declarations such as RoHS and REACH requirements prior to final procurement authorization.

Selection Notes

Select this component when designing compact LED backlight circuits requiring high efficiency and minimal external component count. The integrated synchronous rectifier reduces board space compared to solutions using discrete diodes. Consider the 1.05 MHz switching frequency for optimizing inductor size while maintaining stable operation across the specified load conditions.

Part Context

This part belongs to the MP3412 series of power management ICs designed specifically for white LED driving applications. It represents a specialized subset of Monolithic Power Systems' synchronous boost converter portfolio, optimized for low-voltage input sources common in single-cell battery-powered consumer electronics.
