## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference and source terminal of low-side power MOSFET; connect as single-point junction for feedback networks to avoid ground noise coupling. |
| 2 | SW | output | Switch node connection between high-side and low-side power MOSFETs; connects to external output inductor; voltage rating -2 V to 19 V (transient: -3.5 V to 21 V). |
| 3 | VIN | power_in | Input voltage supply and drain terminal of high-side power MOSFET; recommended operating range 4.5 V to 17 V with 10 µF minimum ceramic decoupling capacitor. |
| 4 | PG | output | Power Good open-drain output indicating converter output regulation; active high when output voltage within ±10% of target threshold; requires external pull-up resistor. |
| 5 | SS | input | Soft-start control input; external capacitor to GND sets soft-start ramp time using internal charge current of 6 µA typical; operating voltage range -0.1 V to 5 V. |
| 6 | VFB | input | Feedback voltage input for output regulation via resistor divider; regulation threshold 0.765 V typical at 25°C (range 758-772 mV over temperature); input current ±0.1 µA. |
| 7 | EN | input | Enable control logic input; active high enables converter; logic high threshold 1.6 V, low threshold 0.6 V; internal pull-up resistance 225-900 kΩ to VIN. |
| 8 | VBST | power_in | Bootstrap supply for high-side MOSFET gate driver circuit; connect 0.1 µF ceramic capacitor to SW pin; operating voltage range -0.1 V to 23 V (6 V maximum relative to SW). |
