Working Principles

The ADP2301AUJZ-R2 is a synchronous step-down voltage regulator that converts a higher input voltage to a lower output voltage. It utilizes a pulse-width modulation (PWM) control scheme to regulate the output voltage. The EN pin enables or disables the regulator, while the FB pin provides feedback to adjust the output voltage.

The SW pin connects to an external inductor and capacitor to form a buck converter, which efficiently steps down the input voltage. The LX pin is connected to the low-side MOSFET switch of the regulator. The PGND pin serves as the power ground reference, while the GND pin is the signal ground reference.
