1 EN Enable Input. This pin enables control for the ADP2360 with precision thresholds. 2 PG Power-Good Output. This pin is an open-drain, power-good indicator. 3 ITH IPEAK Threshold Programming Pin. Connect a resistor to ground to adjust the IPEAK level in the application. 4 FB Output Voltage Feedback Input. Use this pin to set the output voltage. 5 SS Soft Start. Connect a capacitor from SS to AGND to adjust the soft start time of the device. 6 PGND Power Ground. NMOS power device and driver ground connection. 7 SW Switch Node. This pin is the drain of the power NMOS and power PMOS devices. 8 VIN Input Voltage. An input capacitor must be placed between this pin and PGND. 9 AGND (EPAD) Analog Ground. The exposed pad must be connected and soldered to an external ground plane. Rev.
