Working Principles

The LTC3803MPS6-5#TRMPBF operates as a synchronous step-down DC/DC controller. It regulates the output voltage by adjusting the duty cycle of the internal power switches. The feedback pin (FB) monitors the output voltage and compares it to a reference voltage, generating an error signal. This error signal is then used to adjust the duty cycle, ensuring the output voltage remains within the desired range. The current mode control architecture provides stability and protection against overcurrent conditions.
