MPQ1530DQ-LF-P

Overview

The MPQ1530DQ-LF-P is a triple output step-up converter with linear regulators designed for TFT bias applications. It operates from an input voltage range of 2.7V to 5.5V and provides a step-up output up to 22V, a positive 20mA linear regulator, and a negative 20mA linear regulator. The device features a 2.8A switch current limit, 250mΩ internal power MOSFET, 95% efficiency, and a 1.4MHz fixed frequency. It includes internal power-on sequencing, adjustable soft-start/fault timer, cycle-by-cycle over-current protection, under-voltage lockout, and a ready flag in a 16-pin QFN (3mm x 3mm) package.

Feature Summary

Integrates triple output step-up converter with linear regulators for complete DC/DC solution
Features internal power-on sequencing and adjustable soft-start/fault timer
Includes cycle-by-cycle over-current protection and under-voltage lockout

Applications

TFT LCD Displays
Portable DVD Players
Tablet PCs
Car Navigation Displays

Procurement Notes

Verify the exact suffix 'LF-P' against official MPS documentation to confirm lead-free status and tape-and-reel packaging specifications. Confirm RoHS compliance and moisture sensitivity level (MSL 1) requirements for your assembly process. Ensure the 16-QFN package dimensions match your PCB footprint design constraints.

Selection Notes

Select this component when a single IC solution is required to power TFT LCD panels from regulated 3.3V or 5V supplies. Consider its 1.4MHz switching frequency for compact external component sizing. Evaluate the 2.8A current limit and 250mΩ RDS(on) for thermal management in space-constrained portable devices.

Part Context

The MPQ1530DQ-LF-P belongs to the MP1530 family of PMICs from Monolithic Power Systems. It is specifically engineered as a specialized voltage regulator for display bias circuits. The device consolidates multiple power stages into one package to reduce board space and simplify design for mobile and automotive display applications.
