TP6811S5 from TECH PUBLIC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input. Turns the converter on/off. Logic-high (>=1.5V) enables; logic-low (<=0.4V) disables. Internal pull-low resistance ~950 kOhm. |
| 2 | GND | power_in | Power ground pin. Return path for input current and internal circuitry. |
| 3 | SW | output | Switching node. Connect to the external inductor. Internally driven by the high-side and low-side MOSFETs (Rds(on) ~150 mOhm / ~130 mOhm), with 2.4A typical high-side current limit. |
| 4 | VIN | power_in | Power input pin. Supplies the internal MOSFETs and control circuitry. Operating range 2.7V to 5.5V (absolute max 6V). Bypass with a ~10uF ceramic capacitor to GND. |
| 5 | FB | input | Output feedback pin. Connects to the resistor divider from Vout that sets the output voltage. Regulates to VREF = 0.6V typical (0.591-0.609V). |
