What is the working principle of the 9907-165 digital voltage regulator?

The working principle of the digital voltage regulator is to convert the input voltage into a stable output voltage to meet the voltage requirements of different devices. It mainly adjusts the output voltage by controlling the motor and changing the coil tie ratio.

What is the accuracy of 9907-165 digital voltage regulator?

The accuracy of digital voltage regulator is mainly affected by two factors:

Sampling accuracy: The higher the sampling accuracy, the higher the accuracy of the regulator. In general, the sampling frequency of the digital regulator can reach tens of kilohertz, and the sampling accuracy can reach the millivolt level.

Control algorithm: The quality of the control algorithm directly determines the accuracy and stability of the regulator. Some advanced digital voltage regulators adopt adaptive control algorithm, which can automatically adjust the output voltage according to the change of the input voltage, so as to improve the accuracy and stability of the voltage regulator.

In general, the accuracy of the 9907-165 digital regulator can reach 0.1%~0.5%, and for some high-precision applications, the accuracy can reach 0.01% or even higher.
