TPS54328DDAR 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 | Enable input control, active high with logic high threshold of 1.6 V and low threshold of 0.45 V. |
| 2 | VFB | input | Converter feedback input with threshold voltage of 765 mV in continuous mode, connect to output voltage divider. |
| 3 | VREG5 | power_out | Regulated 5.5-V power output (5.2-5.7 V typical, 60 mA maximum) requiring 1-µF bypass capacitor to GND. |
| 4 | SS | input | Soft-start control input with 2-µA typical charge current (1.4-2.6 µA range) for external capacitor to GND. |
| 5 | GND | power_in | Ground and power return pin serving as single-point connection for sensitive SS and VFB signal returns. |
| 6 | SW | output | Switch node connection between high-side and low-side N-channel MOSFETs driving the output inductor. |
| 7 | VBST | input | Bootstrap supply input for high-side gate drive requiring 0.1-µF capacitor between VBST and SW, charged by internal diode from VREG5. |
| 8 | VIN | power_in | Input voltage supply pin with operating range of 4.5-18 V supplying main converter power. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
