TPS54227DDAR from Texas Instruments, in a HSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input; active high; must be pulled up to enable device. |
| 2 | VFB | input | Feedback input for output voltage control via resistor divider. |
| 3 | VREG5 | power_out | 5.5-V regulated power output; connect 1-µF capacitor to GND; not active when EN is low. |
| 4 | SS | output | Soft-start control output; connect external capacitor to GND for adjustable soft-start time. |
| 5 | GND | power_in | Power ground return for switching circuit; connect SS and VFB returns at single point. |
| 6 | SW | output | Switch node between high-side and low-side NFET. |
| 7 | VBST | input | Bootstrap supply input for high-side gate driver; connect 0.1-µF capacitor between VBST and SW; internal diode to VREG5. |
| 8 | VIN | power_in | Input voltage supply pin; operating range 4.5-V to 18-V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
