XC6221A252MR-G Integrated Circuits (ICs)

PMIC - Voltage Regulators - Linear

The XC6221A252MR-G is an integrated circuit developed by Sumida Electric and widely used as a linear voltage regulator. It is a Voltage Regulator Manager (VRM) that helps to maintain the steady supply of a source voltage, in this case a 2.5V output from a 3V input. Its stable voltage output, high output current and low power consumption makes it suitable for a wide range of applications.

Application Field

The XC6221A252MR-G is a versatile IC, suitable for a wide range of application fields. It is designed for use in small, handheld devices, such as cell phones, multimedia players and digital cameras, as well as larger applications such as laptops and servers. Additionally, it is suitable for RF applications, with its high level of voltage control and small size making it an ideal choice.

It can also be used in power supplies of industrial systems, as well as automotive applications. Finally, the integrated circuit is an ideal choice in video hub applications, with its tight voltage regulation, high power output and low power consumption.

Working Principle

The XC6221A252MR-G works by converting the input voltage into a regulated output voltage. The input voltage is first filtered by a low-pass filter, which removes any high frequency noise. The filtered voltage is then converted into an adjustable output voltage through a series of operational amplifiers and voltage regulators.

The output voltage is then further stabilized by an error amplifier, which monitors the output voltage and adjusts the feedback loop accordingly. The output voltage is then transferred to a high-power buffer, which provides the final output voltage at the required level.

The XC6221A252MR-G has a wide range of adjustable output voltage from 1.8V to 5V, with a maximum output current of 1A and a high power density of around 6W per device. This makes it a very versatile and reliable voltage regulator.

Conclusion

The XC6221A252MR-G is a versatile, reliable and high-performance Voltage Regulator Manager (VRM) manufactured by Sumida Electric. It is capable of supplying a 2.5V output from a 3V input and suitable for a wide range of applications, including small handheld devices, RF applications, power supplies of industrial systems, automotive applications, and video hub applications. Its wide adjustable output voltage, high output current and low power consumption makes it the perfect choice for any application.
