TPS54528DDAR from Texas Instruments, in a SOIC-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 | Active-high enable input with logic thresholds at 0.6 V (low) and 1.6 V (high). |
| 2 | VFB | input | Converter feedback input for output voltage regulation at 765 mV nominal threshold. |
| 3 | VREG5 | power_out | Internal regulated 5.5 V power supply output (5.2 to 5.7 V typical) with maximum 60 mA output current. |
| 4 | SS | input | Soft-start control input; external capacitor should be connected to GND for adjustable startup time. |
| 5 | GND | power_in | Power ground return for switching circuit; sensitive analog signals must reference here. |
| 6 | SW | output | Power stage switching node between high-side and low-side MOSFETs; operating range -1.8 V to 18 V. |
| 7 | VBST | power_in | Bootstrap supply for high-side FET gate drive with internal diode to VREG5; bypass with 0.1 µF capacitor to SW. |
| 8 | VIN | power_in | Main supply input voltage; recommended operating range 4.5 V to 18 V. |
| 9 | Exposed Thermal Pad | power_in | Thermal dissipation pad connected to GND; must be soldered to PCB for proper heat management. |
