# TPS560430YDBVT

**Texas Instruments** · DC-DC Converters · SOT-23-6

TPS560430YDBVT from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CB | passive | Bootstrap capacitor connection for high-side FET driver; connect a high quality 100-nF capacitor from this pin to the SW pin. |
| 2 | GND | power_in | Power ground terminal connected internally to source of low-side FET; connect to system ground, ground side of CIN and COUT with path to CIN as short as possible. |
| 3 | FB | input | Feedback input to the converter; connect a resistor divider to set the output voltage and never short this terminal to ground during operation. |
| 4 | EN | input | Precision enable input to the converter; do not float, High = on, Low = off, can be tied to VIN, and allows adjustable UVLO by external resistor divider. |
| 5 | VIN | power_in | Supply input terminal to internal bias LDO and high-side FET; connect to input supply and input bypass capacitors CIN with direct connection. |
| 6 | SW | output | Switching output of the converter internally connected to source of high-side FET and drain of low-side FET; connect to power inductor. |
