TP6811S5

TECH PUBLIC · DC-DC Converters · SOT-23-5

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).
