Analog ground, reference ground for the IC. Follow PCB routing notes for
connecting this pin.
Output voltage sense pin. Connect to V
regulation.
Enables switcher when HIGH, shutdown mode when LOW. This pin should not
be left floating.
Analog control input from an external D-to-A converter.
Analog bias supply voltage input. Connect to PVIN.
Connect to analog ground.
Force bypass transistor when HIGH; auto-bypass when LOW. This pin should
not be left floating
External clock synchronization input and PFM lockout. When SYNC remains
HIGH, the DC-to-DC does not allow PFM mode. Tie SYNC to AGND if not used.
Power ground of the internal MOSFET switches. Follow routing notes for
connections between PGND and AGND.
Switching node of the internal MOSFET switches. Connect to output inductor.
Supply voltage input to the internal MOSFET switches. Connect to input power
source.
