MP2224GJ-Z

The MP2224GJ-Z range of voltage regulators from Monolithic Power Systems’ Device Solutions range are DC to DC switching regulators.

MP2224GJ-Z regulators offer a wide range of features including adjustable output voltage, over-temperature protection, current limit and under voltage lockout protection. They have a wide input voltage range of 4V to 60V, and up to a 4A output current.

The MP2224GJ-Z is a highly efficient and affordable step-down switching regulator. It is designed to efficiently convert and regulate a 3.6V to 56V input supply voltage down to an adjustable output voltage that can be set with onboard resistors.

They are designed for applications such as automotive, industrial, and telecommunications equipment. These voltage regulators provide high efficiency and low power consumption. The MP2224GJ-Z series has a low ripple noise and low quiescent current to provide optimum performance in any application.

General Working Principle

The MP2224GJ-Z is a synchronous step-down DC-DC voltage regulator that can be used to convert a higher voltage, such as 5V to 3.3V. It operates in two steps. First a higher voltage is applied to the input side and then the voltage is converted and regulated to a lower output voltage. This is accomplished through regulated switching of the MOSFETs (Metal-Oxide Semiconductor Field-Effect Transistors) to get the desired output voltage.

More specifically, the controller uses two switch MOSFETs, one transmitting energy from the input to the output and the other working as a signal to the input to control how much energy is transmitted from the input to the output. The two MOSFETs work in tandem together to create a pulse width modulation (PWM) signal which turns the output voltage on and off at an adjustable frequency.

When the input voltage is higher than the output voltage, the controller turns the switch on, allowing current to pass through the output and thus increasing the output voltage. Once the output voltage reaches the desired level, the controller turns the switch off, stopping any more current from passing to the output thus maintaining the output voltage. This process is then repeated continuously and thus the output voltage is regulated and maintained at the desired level.

MP2224GJ-Z switching regulators are equipped with built-in protections such as over voltage, under voltage, and over temperature protection. These features add to the safety and performance of the device.

Applications

The MP2224GJ-Z is a popular choice for many applications due to the wide range of features it provides. The most common applications include automotive, industrial, and telecommunications equipment, or any application that needs an adjustable voltage output between 3.3V and 5V.

The device is also suitable for powering medical equipment and consumer electronics such as tablets, laptops, and mobile phones. The high efficiency and low quiescent current of the device makes it perfect for use in battery operated products such as digital thermometers, smartwatches and fitness devices.

Overall, the MP2224GJ-Z is an excellent choice for a wide range of applications and can provide reliable, efficient and safe power.
