PMIC - Voltage Regulators - DC DC Switching Regulators

DC-DC switching regulators, more commonly referred to as switch mode power supply (SMPS) units, are electronic circuits used to convert one DC power source to another, usually at a different voltage. The MPQ4568GQ-Z is designed to meet the demands of a wide range of industrial, automotive, computing, and consumer applications.

The MPQ4568GQ-Z is a monolithic high-side, synchronous buck converter which operates from a 2.5V to 40V input voltage range. It can operate at high switching frequencies up to 2.5MHz, and provides a fixed 5V/3A output. The device is also designed to feature integrated under-voltage lockout, short-circuit protection, over-temperature protection and synchronous rectified MOSFETs for reduced losses and improved efficiency.

The MPQ4568GQ-Z is a step down switching regulator and operates by controlling the on and off times of a pair of internal MOSFETs. This allows the input voltage to be switched rapidly between the output voltage and a reference voltage to produce the desired output. The reference voltage is generated inside the device and can be adjusted externally to ensure the output remains stable over temperature and line variations. The device also includes an internal compensating network which allows for fast transient response and for regulation over line, load, and temperature variations.

The MPQ4568GQ-Z is well-suited for applications such as automotive, computing, and consumer electronics, where the output voltage must remain stable over a wide range of line, load, and temperature conditions. The device is also designed to handle transients and fast load changes, making it ideal for applications such as power supplies, point of load converters, and other systems that require high performance.

The MPQ4568GQ-Z is a highly efficient, low-noise, step-down switching regulator that offers an ideal combination of performance and feature integration for a wide range of industrial, consumer and automotive applications. The device is easy to configure and delivers reliable operation, enabling users to quickly and easily design systems that can meet the most demanding design requirements.
