## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PGND | power_in | Power ground node; must be soldered to ground plane and exposed thermal pad for adequate dissipation and mechanical reliability. |
| 2 | VIN | power_in | Power supply input; rated for operating voltages from 3V to 17V per device specifications. |
| 3 | EN | input | Enable logic input; high level activates converter operation, low level triggers shutdown mode. |
| 4 | AGND | power_in | Analog ground reference point for feedback divider network and internal control circuitry. |
| 5 | FB | input | Feedback voltage input for adjustable output versions; internally compared to 0.8V reference. |
| 6 | VOS | input | Output voltage sense input; supplies feedback signal to internal compensation network. |
| 7 | SW | output | Switching node output driven by internal high and low-side MOSFETs; connects to external inductor. |
| 8 | PG | output | Open-drain power good output indicating output voltage regulation status; goes high impedance when device is disabled. |
| 9 | Exposed Thermal Pad | power_in | Thermal dissipation interface connected to AGND; must be soldered to PCB ground plane for adequate heat removal. |
