MP1531DM-LF-P

Overview

The MP1531DM-LF-P is a low-power triple output step-up switching regulator designed for TFT LCD bias applications. It operates from an input voltage range of 2.7 V to 5.5 V and provides three adjustable outputs ranging from 2.7 V to 22 V. The device features a fixed switching frequency of 250 kHz and delivers up to 500 mA output current. It utilizes a TSSOP-16 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a triple output step-up converter architecture optimized for powering TFT LCD panels.
• Supports configurable operation allowing output voltages to be adjusted across a wide range.
• Utilizes current-mode control for stable performance in compact power solutions.

Applications

• TFT LCD panel bias power supply
• Low power portable display systems
• Consumer electronics with integrated displays

Procurement Notes

Verify the specific suffix 'P' indicates tape-and-reel packaging, distinct from the 'Z' variant which may use different packaging. Confirm RoHS compliance status matches project requirements. Ensure the TSSOP-16 footprint aligns with PCB design constraints. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or thermal guidelines.

Selection Notes

Select this component when a single-chip solution is required for multiple bias rails in display applications. It is suitable for designs needing adjustable high-voltage outputs from a low-voltage source. Consider the 250 kHz switching frequency for EMI management and inductor size trade-offs. Evaluate the 500 mA current capability against total load requirements for all three outputs.

Part Context

This part belongs to the MP1531 series from Monolithic Power Systems, specifically engineered for display driver power needs. It complements similar parts like the MP1530, which combines step-up converters with linear regulators. The series focuses on providing complete DC/DC solutions for TFT technologies in space-constrained environments.

Replacement Considerations

The MP1531DM-LF-Z is a pin-compatible alternative with identical electrical specifications but differs in packaging format. Verify that the reel quantity associated with the 'P' suffix meets assembly line requirements if replacing the 'Z' version.
