# TPS560430YQDBVRQ1

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

TPS560430YQDBVRQ1 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 | power_out | Bootstrap capacitor connection for high-side FET driver with voltage rating -0.3 to 5.5 V relative to SW; connect 100nF capacitor to SW pin. |
| 2 | GND | power_in | Power ground terminal connected to low-side FET source internally; connect to system ground and to input/output capacitors ground with minimum trace length. |
| 3 | FB | input | Feedback input to converter with voltage range 0 to 4.5 V; connect resistor divider to set output voltage and do not short to ground during operation. |
| 4 | EN | input | Precision enable input with voltage range 0 to VIN V that must not float; high = on, low = off; allows adjustable UVLO via external resistor divider. |
| 5 | VIN | power_in | Supply input terminal to internal bias LDO and high-side FET with voltage range 4 to 36 V; connect input supply and bypass capacitors CIN directly to this pin and GND. |
| 6 | SW | power_out | Switching output of converter with voltage rating -0.3 to VIN+0.3 V nominal or -3.5 to 38 V for transients less than 10 ns; internally connected to high-side FET source and low-side FET drain; connect to power inductor. |
