# TPS60313DGSR

**Texas Instruments** · DC-DC Converters · VSSOP-10-0.5mm

TPS60313DGSR 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 | SNOOZE | input | Snooze mode enable input: pulling it low enables snooze mode at low output current, and pulling it high disables snooze mode. |
| 2 | C1- | passive | Negative terminal of the flying capacitor C1F. |
| 3 | VIN | power_in | Supply input for a 0.9 V to 1.8 V input range; bypass VIN to GND with a capacitor of at least 1 µF. |
| 4 | C1+ | passive | Positive terminal of the flying capacitor C1F. |
| 5 | OUT1 | power_out | 2 × VIN power output, rated for a maximum of 40 mA when OUT2 is not loaded; bypass to GND with the output filter capacitor C(OUT1). |
| 6 | OUT2 | power_out | Regulated 3-V power output on the TPS60313, rated for a maximum of 20 mA when OUT1 is not loaded; bypass to GND with the output filter capacitor C(OUT2). |
| 7 | C2+ | passive | Positive terminal of the flying capacitor C2F. |
| 8 | C2- | passive | Negative terminal of the flying capacitor C2F. |
| 9 | GND | power_in | Ground reference for the device. |
| 10 | PG | output | Power-good output that goes high when OUT2 reaches about 98% of its nominal value; on the TPS60313 it is a push-pull output, and any current drawn from PG reduces the maximum OUT2 output current. |
