Pin Descriptions

Pin Number

Name

Description

1

VIN

Power supply input. A low ESR input capacitance should be located as close as possible to the VIN

pin and exposed pad (EP).

2

EN

Active high enable input for the device.

3

SS

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.

4

GND

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.

5

FB

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.

6, 7

VOUT

The output terminal of the internal inductor. Connect the output filter capacitor between VOUT pin and

EP.

EP

Exposed

Pad

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.
