XC6220B28BPR-G

PMIC, or Power Management Integrated Circuits, is a class of electronic components, designed to efficiently manage a power supply network. PMICs are designed to regulate voltage levels and provide current control, clock regulation, power sequencing, voltage multiplier, or a combination of all. XC6220B28BPR-G is an example of a linear PMIC and will be discussed in further details in this article.

Application Field

Linear PMICs are designed to control voltage, typically in a linear fashion. XC6220B28BPR-G is a combination of a voltage regulator and a current limiter, allowing voltage level to be stepped up or down with a controllable current limit. As such, XC6220B28BPR-G can be used for a variety of applications, including power supply for communication terminals, finance and security systems, smart home and Office equipment.

Working Principle

XC6220B28BPR-G is based on a linear regulator design, with several key features. The regulator is designed to produce a stable, regulated output voltage regardless of incoming voltage variations, load and ambient temperature. The two external resistors R1 and R2 of the circuit are responsible for setting the output voltage. The output voltage equals the voltage of R1, divided by the sum of resistance of R1 and R2.

To provide current control and limiting, the regulator is also integrate into a feedback loop. When the load current is limited, the feedback loop encourages to reduce the total load current. Conversely, when the load current is increased, the current loop increases the total load current. This is the main advantage of using XC6220B28BPR-G as a power supply, since the current limit will ensure power supply reliability while also avoiding damage to the connected equipment.

In addition, XC6220B28BPRG also provides protection against overvoltage, overcurrent and overtemperature. These protection module ensure the safety of all connected devices, by shutting down the power supply when certain conditions are met. This feature make XC6220B28BPRG a perfect choice for systems requiring a high degree of reliability in power supply management.

Conclusion

In conclusion, XC6220B28BPRG is a perfect example of a linear PMIC, with a range of features and protections to ensure reliable and consistent power supply for connected devices. The two main features of XC6220B28BPRG, voltage regulation and current limitation, coupled with protection features make it a popular choice for a variety of systems.
