TPS60503DGS from Texas Instruments, in a VSSOP-10-0.5mm. 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 | EN | input | Device-enable input; EN high disables the device (output and input isolated in shutdown), EN low enables it. |
| 2 | PG | output | Open-drain power good output that goes high once OUT reaches about 97% of its nominal value; leave unconnected if unused. |
| 3 | C2F− | passive | Negative terminal of the flying capacitor C2F. |
| 4 | C2F+ | passive | Positive terminal of the flying capacitor C2F. |
| 5 | VIN | power_in | Supply input; connect to an input supply in the 1.8-V to 6.5-V range. |
| 6 | C1F+ | passive | Positive terminal of the flying capacitor C1F. |
| 7 | OUT | power_out | Regulated 1.5-V power output for TPS60503; bypass OUT to GND with the output filter capacitor Co. |
| 8 | C1F− | passive | Negative terminal of the flying capacitor C1F. |
| 9 | GND | power_in | Ground. |
| 10 | FB | input | Feedback pin; for TPS60501 to TPS60503 connect directly to VO. |
