# TPS563219ADDFR

**Texas Instruments** · DC-DC Converters · TSOT-23-8

TPS563219ADDFR from Texas Instruments, in a TSOT-23-8. 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, the source terminal of the low-side power NFET and the ground for the controller circuit, to be connected to the sensitive VFB ground at a single point. |
| 2 | SW | power_out | Switch node connection between the high-side NFET and the low-side NFET. |
| 3 | VIN | power_in | Input voltage supply pin and the drain terminal of the high-side power NFET. |
| 4 | PG | output | Power good open-drain output. |
| 5 | SS | passive | Soft-start control; an external capacitor should be connected between this pin and GND. |
| 6 | VFB | input | Converter feedback input; connect to the output voltage through a feedback resistor divider. |
| 7 | EN | input | Enable input control, active high; it must be pulled up to enable the device. |
| 8 | VBST | power_in | Supply input for the high-side NFET gate drive circuit; connect a 0.1 µF capacitor between VBST and SW. |
