It can provide up to 12 voltage ranges so as to simplify the design process required in server and storage system with mixed voltage requirements. In addition, it also provides low-voltage system design flexibility, making it an ideal solution for building energy efficient servers or storage system.

Working Principle

UCS2112T-1-V/G4 is able to control the power output in the system by using a switched-mode power supply. It is based on the principle of voltage regulation and consists of two main parts - input voltage and output voltage. The input voltage is the power source for UCS2112T-1-V/G4 and the output voltage is the power that supplies the target device.In order to reach its maximum performance, UCS2112T-1-V/G4 uses a feedback loop configuration from the output voltage to the input voltage, which power the devices and produces an output voltage at the exact level that is required for its operation. With the help of this feedback loop, UCS2112T-1-V/G4 is capable to constantly monitor and adjust the input voltage in order to maintain a stable output.The UCS2112T-1-V/G4 also has a built-in current-monitoring feature to increase the efficiency of the power management system. This feature is particularly useful in power-hungry applications such as servers, RAID buses or network computing. Furthermore, it also features built-in over-current protection, thermal shutdown and power-failure protection.

Conclusion

UCS2112T-1-V/G4 is an integrated PMIC circuit specifically designed to control up to 12 voltage outputs for computing and communication applications. With its built-in feedback loop and current-monitoring feature, it is able to provide a stable and efficient power management system for these devices. Furthermore, it also offers a variety of protection features to ensure reliable operation of the system.
