MPQ2019GN-33-AEC1

Introduction

This article will discuss the MPQ2019GN-33-AEC1 application field and working principle in the context of linear PMIC (Power Management Integrated Circuits) voltage regulators. PMIC voltage regulators are an important component of electronic circuits, responsible for controlling the voltage and current of an electronic system. Linear PMIC voltage regulators in particular, feature low-noise operation and adjustable output voltage, making them well suited for applications such as digital audio processing and DSP (Digital Signal Processing).

Overview

MPQ2019GN-33-AEC1 is a linear PMIC voltage regulator produced by Macroblock Inc. It is a single-channel, dual-mode voltage regulator with adjustable output voltage, and is available in a SOIC-8 package. It offers up to 18V output voltage in the normal mode, and up to 395mV in the reduced-noise mode. The MPQ2019GN-33-AEC1 can support up to 2A load current in each output channel, and features high switching frequency of up to 5MHz. It is designed for use in applications such as LCD/LED driving, battery charging and DC/AC adapter powering.

Working Principle

The MPQ2019GN-33-AEC1 voltage regulator functions as a linear regulator, which provides a regulated and constant output voltage. The regulator uses an external reference voltage source, usually connected to a resistor divider, to determine the desired output voltage. The differential input voltage is then compared with the reference voltage and amplified by an internally generated gain. The amplified signal is used to turn on an internal P-channel MOSFET, which is then used as the main pass-element for the regulator.

The output voltage of the regulator is then controlled by the gate drive for the MOSFET, which is determined by the feedback signal. The output voltage is kept at the desired level by continuously adjusting the MOSFETs gate voltage with the built-in error amplifiers. This enables the voltage regulator to maintain a stableoutput voltage in spite of variations in the input voltage and load currents.

Advantages

The MPQ2019GN-33-AEC1 linear PMIC voltage regulator offers many advantages over other PMIC voltage regulators: it offers up to 18V output, which is ideal for applications such as power supplies and LCD/LED driving; its high switching frequency of up to 5MHz ensures faster response times and better efficiency; it is available in a compact SOIC-8 package, allowing it to be easily soldered onto a circuit board; and it offers adjustable output voltage, which allows the designer to optimize the output voltage to fit the application.

Conclusion

The MPQ2019GN-33-AEC1 linear PMIC voltage regulator is an excellent choice for applications that require stable, adjustable output voltage, such as LCD/LED drivers, power supplies, and battery chargers. Its adjustable output voltage, high switching frequency, and compact SOIC-8 package makes it a great choice for any electronic design.
