Description
Mode Select. This pin toggles between auto mode (PFM and PWM switching) and PWM mode. Set MODE low to
allow the part to operate in auto mode. Pull MODE high to force the part to operate in PWM mode. The voltage
applied to MODE should never be higher than the voltage applied to VIN. Do not leave this pin floating.
Switch Node.
Feedback Divider Input. Connect the output capacitor from FB to GND as close as possible to the ADP2121 to set
the output voltage ripple and to complete the control loop.
Power Supply Input. Connect the input capacitor from VIN to GND as close as possible to the ADP2121.
Enable. Pull this pin high to enable the part. Set this pin low to disable the part. Do not leave this pin floating.
Ground Pin.
