MPQ1530DQ-LF-Z

Overview

The MPQ1530DQ-LF-Z is a switching voltage regulator manufactured by Monolithic Power Systems. It features a triple output step-up (boost) topology with an integrated linear regulator section, designed for TFT bias applications. The device operates with an input voltage range of 2.7 V to 5.5 V and provides adjustable outputs up to 22 V. It utilizes a 1.4 MHz switching frequency and is housed in a 16-lead VFQFN EP package. The component supports surface mount installation and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Integrates a triple output step-up converter with linear regulators for complete DC/DC solutions
• Supports adjustable operation from 2.7 V to 22 V for flexible power delivery
• Operates at a high switching frequency of 1.4 MHz for compact design

Applications

• TFT LCD panel power supply
• TFT bias generation circuits
• Low power three-output step-up converters

Procurement Notes

Verify the specific suffix and package type against official datasheets before procurement. Confirm that the 16-lead VFQFN EP footprint matches the target PCB layout. Ensure compatibility with the required operating temperature range of -40°C to 125°C. Cross-reference the manufacturer part number to avoid confusion with similar non-Q or LF variants.

Selection Notes

Select this component when a combined boost and LDO solution is required for display biasing. The 1.4 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the input voltage range of 2.7 V to 5.5 V aligns with the system power source. Consider the thermal performance of the exposed pad package for heat dissipation requirements.

Part Context

This part belongs to the MP1530 family of power management ICs from Monolithic Power Systems. It is specifically engineered for driving Thin Film Transistor Liquid Crystal Display panels. The integration of multiple regulation stages reduces the overall component count in portable electronic devices requiring stable display voltages.
