# TPS62056DGS

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

TPS62056DGS 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 | VIN | power_in | Supply voltage input. |
| 2 | LBO | tri_state | Open-drain low battery output; logic low signal indicates a low battery voltage. |
| 3 | GND | power_in | Ground. |
| 4 | PG | tri_state | Power good comparator output, open-drain; output floats when output voltage is greater than 95% of nominal value. |
| 5 | FB | input | Feedback pin for fixed output voltage option; external resistive divider for adjustable version. |
| 6 | LBI | input | Low battery input. |
| 7 | SYNC | input | Input for synchronization to external clock signal (600 kHz to 1.2 MHz); determines PWM/PFM mode operation. |
| 8 | EN | input | Enable input; logic high enables converter, logic low forces shutdown mode reducing supply current to less than 2 µA. |
| 9 | SW | output | Switch pin connected to inductor; drain of internal power MOSFETs. |
| 10 | PGND | power_in | Power ground; connect all power grounds to this pin. |
