TPS62821DLCR from Texas Instruments, in a VSON-8(1.5x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input; high enables operation, low disables; do not leave floating. |
| 2 | FB | input | Output voltage feedback input; connect resistive voltage divider to set output voltage. |
| 3 | AGND | power_in | Analog signal ground, internally connected to PGND, can be left floating. |
| 4 | NC | unconnected | Internally not connected; can be connected to VOUT, GND, or left floating. |
| 5 | PGND | power_in | Power supply ground. |
| 6 | SW | output | Switch node connected to internal high-side and low-side MOSFET switches; conducts alternating high currents. |
| 7 | VIN | power_in | Supply voltage input, operating range 2.4V to 5.5V. |
| 8 | PG | output | Power good open-drain output with high impedance when output voltage is regulated and low when out of regulation; if unused, leave floating or connect to GND. |
