Power supply input. A low ESR input capacitance should be located as close as possible to the VIN
pin and exposed pad (EP).
Active high enable input for the device.
Soft-start control pin. An internal 2 µA current source charges an external capacitor connected between
SS and GND pins to set the output voltage ramp rate during startup. The SS pin can also be used to
configure the tracking feature.
Power ground and signal ground. Provide a direct connection to the EP. Place the bottom feedback
resistor as close as possible to GND and FB pin.
Feedback pin. This is the inverting input of the error amplifier used for sensing the output voltage. Keep
the copper area of this node small.
The output terminal of the internal inductor. Connect the output filter capacitor between VOUT pin and
EP.
Exposed pad is used as a thermal connection to remove heat from the device. Connect this pad to the
PC board ground plane in order to reduce thermal resistance value. EP must also provide a direct
electrical connection to the input and output capacitors ground terminals. Connect EP to pin 4.
