Working Principle of TPS77350DGKR

The TPS77345DGKR operates by taking power from the input voltage and regulating it with a feedback loop. The feedback loop consists of an error amplifier, a comparator, and a pass transistor. The error amplifier senses the output voltage, and compares it to a reference voltage. If the output voltage is too low, the error amplifier will increase the duty cycle of the pass transistor to increase the output voltage. Similarly, if the output voltage is too high, then the duty cycle of the pass transistor will be decreased to lower the output voltage.

Conclusion

The TPS77350DGKR is a highly efficient and reliable linear voltage regulator designed for use in a wide range of industrial and commercial applications. It features adjustable current limit, low quiescent current, and short circuit and thermal protection, making it suitable for high power applications. It works by using an error amplifier and a pass transistor to regulate the output voltage.
