CS5172GDR8 Working Principle

The CS5172GDR8 is a DC to DC switching regulator integrated with an advanced current mode architecture. It is designed to have wide input voltage ranges and can deliver up to 20A of output current.The input signal to the output is regulated through a conversion process. A first stage signal conditioner, the current sensing amplifier, amplifies the input signal and sends it to the inner circuits. Next, current control loop regulates the current flow in the internal power circuit by comparing the signal from the current sensing amplifier with an integrated reference signal. The reference signal is adjustable to enable the output voltage or current range to be adjusted. Finally, an output voltage feedback loop is used to compare the output voltage signal to the reference and an error signal is generated that is used to adjust the resulting output voltage and current.

Conclusion

The CS5172GDR8 is a high power DC/DC switching regulator from Vishay Intertechnology Inc. This flexible regulator can provide up to 20A of output current with a wide input voltage range, making it suitable for high-current applications in a wide variety of different power system design.
