| Pin | Type(1) | Description | |
|---|---|---|---|
| Name | NO. | ||
| VIN | 1 | P | Input voltage supply pin. Connect the input decoupling capacitors between VIN and GND. |
| SW | 2 | NC | Switch pin of the power stage. Do not connect, leave floating. |
| VOUT | 3 | P | Output connection. Connect recommended output capacitance from VOUT to PGND. |
| PGND | 4 | G | Power ground connection |
| PG | 5 | A | Power-good open drain output. PG pin can be floating. |
| EN | 6 | A | Enable pin of buck converter. Drive EN high to turn on the converter; drive EN low to turn off the converter. Internal pulldown to GND by a resistor. |
| FB | 7 | A | Converter feedback input. Connect to the center tap of the resistor divider between output voltage and ground. |
| VOS | 7 | A | TPSM863253: Converter feedback input. Connect to Vout directly. |
(1) A = Analog, P = Power, G = Ground
