TPS560430XDBVT from Texas Instruments, in a SOT-23-6. 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 | CB | passive | Bootstrap capacitor connection for the high-side FET gate driver. Connect a 100-nF high-quality ceramic capacitor from CB to SW to develop the boot supply that drives the internal high-side NMOS. |
| 2 | GND | power_in | Power ground. Internally connected to the source of the low-side FET. Tie to system ground and to the ground terminals of CIN and COUT; keep the path to CIN as short as possible. |
| 3 | FB | input | Feedback input to the converter's error amplifier. Connect the tap of an external resistor divider from VOUT to GND to program the output voltage (Vref = 0.8 V typical, ±1.5% over -40 to 125 °C). Never short FB to ground during operation. |
| 4 | EN | input | Precision enable input. High = converter on, Low = off; do not float. Can be tied directly to VIN, or driven from a resistor divider on VIN to implement an adjustable input UVLO threshold. |
| 5 | VIN | power_in | Supply input to the internal bias LDO and to the drain of the high-side FET. Operating range 4 V to 36 V. Connect the input bypass capacitor CIN directly between this pin and GND with minimum loop area. |
| 6 | SW | power_out | Switching node. Internally connected to the source of the high-side FET and the drain of the low-side FET. Connect to the power inductor; also serves as the low-side reference for the CB bootstrap capacitor. Delivers up to 600 mA continuous output current. |
