## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOS | input | Output voltage sense pin and connection for control loop circuitry; must connect directly to output capacitor for feedback; operating voltage -0.3 to 7 V. |
| 2 | SW | tri_state | Switch node pin connected to internal MOSFET switches; connect inductor between SW pin and output capacitor; operating voltage -0.3 to (VI + 0.3) V. |
| 3 | SW | tri_state | Switch node pin connected to internal MOSFET switches; connect inductor between SW pin and output capacitor; operating voltage -0.3 to (VI + 0.3) V. |
| 4 | PG | tri_state | Open-drain power-good output pin; requires external pullup resistor; maximum sink current 2 mA; operating voltage -0.3 to 7 V. |
| 5 | FBS | input | Output-voltage feedback sense pin for positive remote sensing of load voltage; must connect close to load supply node; operating voltage -0.3 to 3 V. |
| 6 | AGND | power_in | Analog ground pin; must connect directly to exposed thermal pad and common ground plane for proper circuit operation. |
| 7 | SS | output | Soft-start output pin; external capacitor connected to this pin sets the soft-start time for controlled output voltage ramp; operating voltage -0.3 to 7 V. |
| 8 | VID1 | input | Output-voltage selection input pin (VIDx); used for dynamic voltage programming; operating voltage -0.3 to 7 V. |
| 9 | VID0 | input | Output-voltage selection input pin (VIDx); used for dynamic voltage programming; operating voltage -0.3 to 7 V. |
| 10 | AVIN | power_in | Analog supply voltage input for internal control circuitry; must connect to same source as PVIN; operating range 3 to 17 V. |
| 11 | PVIN | power_in | Power supply input pin for internal power stage; operating input voltage range 3 to 17 V; maximum voltage 20 V. |
| 12 | PVIN | power_in | Power supply input pin for internal power stage; operating input voltage range 3 to 17 V; maximum voltage 20 V. |
| 13 | EN | input | Enable/disable logic input pin; internal pulldown resistor maintains low logic level when pin floating; operating voltage -0.3 to 7 V. |
| 14 | LPM | input | Low-power-mode input pin for system standby mode with reduced output voltage; operating voltage -0.3 to 7 V. |
| 15 | PGND | power_in | Power ground pin for high-current return path; must connect directly to exposed thermal pad and common ground plane. |
| 16 | PGND | power_in | Power ground pin for high-current return path; must connect directly to exposed thermal pad and common ground plane. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
