XC6222B301ER-G is a linear regulator with PMIC (Power Management IC). As one type of voltage regulator, it is designed to provide a stable output voltage from a variable input voltage. XC6222B301ER-G can regulate input voltage from 2.3V to 5.5V to output either 1.8V or 1.5V output voltage, guaranteeing a low dropout voltage and offering high efficiency while protecting the system and its load from various possible errors.

Typical applications of XC6222B301ER-G IC include wearable devices, portable handheld products, digital cameras and many other high performance systems that require low profile high efficiency power solutions.

Working Principle

XC6222B301ER-G works on the basic concept of buck converter which is a type of DC-DC conversion that relies on a voltage transfer mechanism. It consists of two switches, connected to each other in series along with an inductor and a diode.

When the switch is on, energy is stored in the inductor. When the switch is turned off, the energy stored in the inductor is used to drive the diode, resulting in a voltage step down or bucking of the supply voltage. This can provide output voltage that is either higher or lower than the input voltage.

XC6222B301ER-G IC has an internal Power-FET that is optimized for low power ripple, high efficiency, low power loss and fast transient response. The chip supports both buck and boost mode with adjustable output voltage from 1.5V to 1.8V and wide input voltage range from 2.3V to 5.5V. It is protected from overcurrent, undervoltage, overvoltage and excessive operating temperature. Furthermore, it has very low drop out and low quiescent current, making it a good choice for battery-powered applications.

Features and Advantages

XC6222B301ER-G IC has a wide range of features such as low quiescent current, a wide input voltage range, and a wide output voltage range. The chip also supports both buck and boost modes. Furthermore, it also has protection features, making it a good choice for battery-powered applications.

One of the major advantages of XC6222B301ER-G is its low-dropout voltage. The device has a low dropout voltage of only ~120mV, which makes it suitable for a wide range of input voltages and therefore allows it to regulate output voltage from a variable input voltage. This low-dropout voltage greatly enhances the charging efficiency, which improves the device\'s overall performance.

Another major feature is its low quiescent current. Low quiescent current is important for battery-powered applications, as it helps to reduce the amount of power being drawn, thus increasing the amount of time that the device can be used on a single charge.

In addition to its low-dropout voltage, XC6222B301ER-G is also capable of providing improved protection against a variety of possible errors. It has overvoltage protection and overcurrent protection, which serves to protect the device and its load from possible errors. It also features a thermal shutdown feature to protect the device from excessive operating temperature.

XC6222B301ER-G IC is an ideal choice for wearable devices, portable handheld products, digital cameras and many other high performance systems that require low profile high efficiency power solutions. Its low-dropout voltage, low quiescent current, wide input and output voltage range, support for buck and boost mode, and protection features make it an ideal choice for such applications.
