Description
Synchronization Input (SYNC). Connect this pin to an external clock between 600 kHz and 1.4 MHz to
synchronize the switching frequency to the external clock (see the Oscillator and Synchronization section for
details).
CCM/PFM Selection (MODE). When this pin is connected to VIN, PFM mode is disabled and the ADP2118 only
works in continuous conduction mode (CCM). When this pin is connected to ground, PFM mode is enabled
and becomes active at light loads.
Frequency Selection. Connect to GND to select 600 kHz and VIN for 1.2 MHz.
Tracking Input. To track a master voltage, drive TRK from a voltage divider from the master voltage. If the
tracking function is not used, connect TRK to VIN.
Feedback Voltage Sense Input. Connect to a resistor divider from V OUT . For the fixed output version, connect
to V OUT directly.
Analog Ground. Connect to the ground plane.
Power Ground. Connect to the ground plane and to the output return side of the output capacitor.
Switch Node Output. Connect to the output inductor.
Power Input Pin. Connect this pin to the input power source. Connect a bypass capacitor between this pin
and PGND.
Bias Voltage Input Pin. Connect a bypass capacitor between this pin and GND and a small (10 Ω) resistor
between this pin and PVIN.
Precision Enable Pin. The external resistor divider can be used to set the turn-on threshold. To enable the part
automatically, connect the EN pin to VIN. This pin has a 1 MΩ pull-down resistor to GND.
Power-Good Output (Open Drain). Connect to a resistor to any pull-up voltage <5.5 V.
The exposed pad should be soldered to an external ground plane underneath the IC for thermal dissipation.
