MP1530DM-LF-P

Overview

The MP1530DM-LF-P is a triple output step-up converter with linear regulators designed for TFT LCD bias applications. It operates from a 2.7V to 5.5V input range and delivers up to 2.8A switch current limit at a fixed 1.4MHz frequency. The device integrates a boost converter capable of reaching 22V, a positive 20mA linear regulator, and a negative 20mA linear regulator within a single package. It utilizes a 16-pin TSSOP or QFN (3x3mm) surface-mount package.

Feature Summary

• Integrates a triple output solution combining a step-up converter with positive and negative linear regulators in one package
• Features internal power-on sequencing and adjustable soft-start timers to manage startup conditions
• Includes cycle-by-cycle overcurrent protection and under-voltage lockout for enhanced reliability

Applications

• TFT LCD displays
• Portable DVD players
• Tablet PCs
• Car navigation displays

Procurement Notes

Verify the specific suffix 'P' against official Monolithic Power Systems documentation to confirm packaging details such as tape and reel specifications. Ensure the component matches the required RoHS compliance status and lead-free designation before procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Selection Notes

Select this component when designing power systems for TFT LCD panels requiring simultaneous positive and negative bias voltages alongside a main boost rail. It is suitable for applications powered by regulated 3.3V or 5V supplies where space constraints favor a single-package solution. Consider the 1.4MHz switching frequency for balancing component size and efficiency requirements.

Part Context

This part belongs to the MP1530 series from Monolithic Power Systems, specialized for display driver power management. The series provides complete DC/DC solutions for powering TFT LCD panels. The DM variant typically denotes the specific pinout and thermal pad configuration compatible with standard surface mount assembly processes for portable electronics.

Replacement Considerations

MP1530DQ-LF-Z is an alternative variant within the same family offering similar triple output functionality.
