NAME

I
Supply voltage for output power stage.
This is the input voltage pin of the device. Connect directly to the input bypass capacitor.
This is the enable pin of the device. Connecting this pin to ground forces the device into shutdown
mode. Pulling this pin to V
I
enables the device. This pin must not be left floating and must be
terminated.
This is the internal reference voltage used to regulate V
. This pin is not connected on fixed output
voltage version of TPS6230xDRC and TPS6232xDRC. Do not connect ADJ pin on fixed output
voltage version of TPS6230xYZD, TPS6231xYZD and TPS6232xYxD.
On TPS62300 and TPS62320, this pin can also be used as an external control input. The output
voltage is 1.5x the applied voltage at ADJ.
This is the feedback pin of the device. For the adjustable version, an external resistor divider is
connected to this pin. The internal voltage divider is disabled for the adjustable version. This pin is
not connected on fixed output voltage version of TPS6230xDRC and TPS6232xDRC. Do not
connect the FB pin on the fixed output voltage version of TPS6230xYZD, TPS6231xYZD and
TPS6232xYxD.
Output feedback sense input. Connect VOUT to the converter’s output.
Analog ground. Connect to PGND via the PowerPAD underneath IC.
Input for synchronization to external clock signal. This pin must not be left floating and must be
terminated. Synchronizes the converter switching frequency to an external clock signal
MODE/SYNC = LOW (GND): The device is operating in fixed frequency pulse width modulation
mode (PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load
currents.
MODE/SYNC = HIGH (VIN): Low-noise mode enabled, fixed frequency PWM operation forced.
Power ground.
This is the switch pin of the converter and is connected to the drain of the internal Power
MOSFETs.
Internally connected to PGND.
