The X40021V14-C application field includes edge computing and embedded applications, wearables, and Internet of Things (IoT). The X40021V14-C’s working principle is based on its integrated buck and boost regulator. The regulator provides a regulated output voltage and current that is used to power the device’s internal circuitry. The regulator\'s output is then compared to an internal reference voltage to generate an error signal. This error signal is used to control the buck/boost regulator to adjust its output voltage and current to maintain the desired voltage and current level. The X40021V14-C also monitors the power rail voltage and current levels and provides the necessary protection when the levels exceed predetermined thresholds.

In summary, the X40021V14-C is a PMIC whose main feature is its ability to provide comprehensive protection to system power rails and to monitor current and voltage levels during system run and standby periods. It is suitable for use in edge computing/embedded applications, wearables, and Internet of Things (IoT). Its working principle is based on its integrated buck and boost regulator that generate a regulated output voltage and current. This output is compared to an internal reference voltage to generate an error signal, which is then used to control the regulator so that the desired voltage and current levels can be maintained.
