Function
Switch node. Connect to the inductor and catch diode.
Signal and power ground pin. Place the bottom resistor of the feedback network as close as possible
to this pin.
Feedback pin. Connect to external resistor divider to set output voltage.
Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN
+ 0.3V.
Input supply voltage.
PIN DESCRIPTIONS 6-Pin WSON
Function
Feedback pin. Connect to external resistor divider to set output voltage.
Signal and power ground pin. Place the bottom resistor of the feedback network as close as
possible to this pin.
Switch node. Connect to the inductor and catch diode.
Power Input supply.
Control circuitry supply voltage. Connect VINA to VIND on PC board.
Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than
VINA + 0.3V.
Connect to system ground for low thermal impedance, but it cannot be used as a primary GND
connection.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Range indicates conditions for
which the device is intended to be functional, but does not ensure specfic performance limits. For specific specifications and test
conditions, see the Electrical Characteristics.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
Thermal shutdown will occur if the junction temperature exceeds the maximum junction temperature of the device.
