The working principle of the TPS71718DCKTG4 is based on linear regulator technology. It uses a voltage feedback loop to regulate the output voltage of the device. The feedback loop works as follows: An input voltage is applied to the device and the internal circuitry converts it to a reference voltage. This reference voltage is compared to the voltage output from the device, and if the output voltage does not match the reference voltage, the feedback loop is triggered. The feedback loop adjusts the output voltage to match the reference voltage by controlling the gate voltage of the internal FETs, which in turn affects the output current of the device. When the output voltage is in accordance with the reference voltage, the feedback loop stops.The TPS71718DCKTG4 also provides integrated voltage feedback resistor, enabling the device to provide an accurate and stable output voltage. Additionally, the device is designed to provide a high level of transient protection in applications where power is transiently overloaded. Conclusion
