MP1530DM-LF-Z

Overview

The MP1530DM-LF-Z is a switching regulator featuring current-mode control and a maximum switching frequency of 1400kHz. It utilizes a PDSO16 package, specifically TSSOP-16, and operates within an input voltage range of 2.7V to 5.5V. The device provides three outputs with a switch current limit of 3.6A and supports adjustable modes from 2.7V to 22V. It employs pulse width modulation technology and includes RoHS compliance.

Feature Summary

• Integrates a triple output step-up converter with linear regulators for complete DC/DC solutions
• Features internal power-on sequencing and adjustable soft-start capabilities
• Includes per-cycle current limiting and undervoltage lockout protection

Applications

• TFT LCD panels
• Portable DVD players
• Tablets
• Automotive navigation displays

Procurement Notes

Verify the specific suffix DM against other variants like DQ or DJ to ensure correct package type (TSSOP vs QFN). Confirm RoHS compliance status and lead times directly with authorized Monolithic Power Systems distributors. Check for obsolescence notices as related family members may have different lifecycle statuses. Ensure ESD handling protocols are followed during installation.

Selection Notes

Select this component when designing power systems for TFT LCD biasing requiring integrated boost and linear regulation. The fixed 1.4MHz frequency allows for compact passive component selection. Verify that the 3.6A switch current limit meets peak load requirements. Consider thermal performance in the TSSOP-16 package for high-duty cycle applications.

Part Context

Manufactured by Monolithic Power Systems, this part belongs to the MP1530 series designed for display driver applications. It combines boost conversion with linear regulation to simplify board layout. The device targets portable electronics and automotive displays where space efficiency and multi-rail generation are critical design constraints.

Replacement Considerations

MP1531DQ-LF-Z serves as a functional alternative within the same family, offering similar triple-output step-up capabilities but housed in a 16-QFN package instead of TSSOP. Verify pin compatibility and thermal characteristics before substitution.
