TPS560430YFDBVR 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 high-quality 100-nF capacitor from CB to SW to develop the boot-strapped supply that turns on the high-side NMOS. |
| 2 | GND | power_in | Power ground terminal, connected internally to the source of the low-side FET. Tie to system ground and to the ground side of CIN and COUT; path to CIN must be as short as possible. |
| 3 | FB | input | Feedback input to the converter (internal reference ~0.8 V ±1.5%). Connect a resistor divider from VOUT to FB to GND to set the output voltage. Never short FB to ground during operation. |
| 4 | EN | input | Precision enable input. High = on, Low = off (threshold ~1.2 V; below 0.95 V shuts the device down). Do not float. May be tied to VIN for self-start, or driven from a resistor divider from VIN to implement an adjustable UVLO. |
| 5 | VIN | power_in | Supply input to the internal bias LDO and to the drain of the integrated high-side FET. Operating range 4 V to 36 V (abs max 40 V). Connect input bypass capacitors CIN directly between this pin and GND. |
| 6 | SW | power_out | Switch-node output; internally the source of the high-side FET and the drain of the low-side FET. Connect to the power inductor. Rated up to 600 mA continuous output current; also serves as the low reference for the bootstrap capacitor. |
