From low-power battery-powered devices to high-power distributed computing systems, the MP3421GG-P offers the ability to optimize design and power delivery for perpetually shifting configurations.

Overview

The MP3421GG-P is a step-up/step-down DC-DC switching regulator with a wide input voltage range from 3.0V to 60V, adjustable and fixed output voltage settings, and up to 2.6A current capability. It features wide duty cycle ranges and protection features for over-load, over-voltage, over-temperature, and input under-voltage lockout. It also incorporates an Adaptive On-Time (AOT) control architecture and a Power Good signal output. The device also offers a soft start and an internal short-circuit current limit.

Applications

The MP3421GG-P is ideal for a range of applications, such as laptop computers, multi-function printers, LCD monitors, and other battery-powered devices that require a high efficiency power supply. In addition, it is also suitable for industrial applications such as motor control and industrial automation, where a wide input voltage range and high-current capability are needed.

Working Principle

The MP3421GG-P works on the principle of switch-mode regulation. It uses an integrated switch to convert the input voltage to the desired output voltage. The switch is activated by the driver, which is controlled by the adaptive on-time (AOT) control architecture. The AOT architecture tracks the feedback voltage and current, and adjusts the duty cycle of the switch to keep the output voltage in regulation. The soft start feature is used to reduce inrush current when the power is initially applied and the Power Good signal output is used to indicate that the output voltage is stable.

The device also has a number of protection features which provide the necessary safety when used in high-power applications. These features include overvoltage, overcurrent, and overtemperature protection. It also has an undervoltage lockout feature to prevent the output voltage from being too low.

Conclusion

The MP3421GG-P is a high-performance DC-DC switching regulator with a wide input voltage range and an adjustable output voltage. It is suitable for a wide range of applications, from low-power battery-powered devices to high-power distributed computing systems. It features a wide duty cycle range and protection features for over-load, over-voltage, over-temperature, and input under-voltage lockout. It also incorporates a soft start and an internal short-circuit current limit. The MP3421GG-P is the ideal power management solution for a variety of design requirements.
