The ADP5054 uses Buck Regulator technology to step down higher input voltages into the required output voltages for each rail. The device offers efficient regulation with current sensing and power-good feedback. The FB pins are used to monitor output voltage, while the EN pins are used to enable or disable the corresponding output regulators.
Each regulator operates independently, and the device can be synchronized with other external clock sources for precise timing control. The VID pins are for identifying the voltage levels for the respective power outputs. Current sensing is done through the ISEN pins, which can provide feedback for overcurrent protection.
