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

TPS562219DDFR 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 serving as source terminal for low-side NFET and reference for controller circuit. |
| 2 | SW | output | Switch node connection between high-side NFET and low-side NFET with operating range -1.8 V to 17 V. |
| 3 | VIN | power_in | Input voltage supply pin and drain terminal of high-side NFET with operating range 4.5 V to 17 V. |
| 4 | PG | tri_state | Power good open-drain output for regulation status indication. |
| 5 | SS | input | Soft-start control pin for external timing capacitor connected to GND with operating range -0.1 V to 5 V. |
| 6 | VFB | input | Converter feedback input for output voltage sensing through resistor divider with operating range -0.1 V to 5.5 V. |
| 7 | EN | input | Enable input control pin, active high, requiring external pull-up to enable device with operating range -0.1 V to 17 V. |
| 8 | VBST | power_in | Supply input for high-side NFET gate drive circuit with 0.1 µF bypass capacitor between VBST and SW pins and operating range -0.1 V to 23 V. |
