# TPS562201DDCT

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

TPS562201DDCT from Texas Instruments, in a TSOT-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 serving as the source of the low-side power NFET and the ground for the controller circuit, and sensitive VFB should be connected to this GND at a single point. |
| 2 | SW | output | Switch node connection between the high-side NFET and the low-side NFET, with the recommended operating range of -1.8 V to 17 V (-3.5 V to 20 V for 10 ns transients). |
| 3 | VIN | power_in | Input voltage supply pin and drain terminal of the high-side power NFET, with a recommended supply range of 4.5 V to 17 V. |
| 4 | VFB | input | Converter feedback input that connects to the output voltage through a feedback resistor divider, with a recommended input range of -0.1 V to 5.5 V. |
| 5 | EN | input | Active-high enable input that must be pulled up to enable the device, with a recommended input range of -0.1 V to 17 V. |
| 6 | VBST | power_in | Supply input for the high-side NFET gate drive circuit, which requires a 0.1 µF capacitor connected between VBST and SW, with a recommended VBST(vs SW) range of -0.1 V to 5.5 V. |
