# TPS561201DDCT

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

TPS561201DDCT 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 | GND | power_in | Ground pin and source terminal of low-side power NFET; connect sensitive VFB to this GND at a single point. |
| 2 | SW | output | Switch node connection between high-side NFET and low-side NFET. |
| 3 | VIN | power_in | Input voltage supply pin (4.5V to 17V), drain terminal of high-side power NFET. |
| 4 | VFB | input | Converter feedback input; connect to output voltage with feedback resistor divider. |
| 5 | EN | input | Enable input control (active high); must be pulled up to enable the device. |
| 6 | VBST | power_in | Supply input for high-side NFET gate drive circuit; connect 0.1-µF capacitor between VBST and SW pins. |
