# TPS62051DGSR

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

TPS62051DGSR 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 operating range 2.7 V to 10 V. |
| 2 | LBO | output | Open-drain low battery output; logic low indicates low battery voltage condition. |
| 3 | GND | power_in | Ground connection for signal and control circuits. |
| 4 | PG | output | Open-drain power good comparator output that floats when output voltage exceeds 95% of nominal value; pull-up resistor must be connected to VOUT. |
| 5 | FB | input | Feedback pin for adjustable output version with external resistive divider or internal voltage divider for fixed output version. |
| 6 | LBI | input | Low battery input for detecting low battery voltage condition. |
| 7 | SYNC | input | Input for external clock synchronization (600 kHz to 1.2 MHz) or control selection between fixed PWM and PWM/PFM operating modes. |
| 8 | EN | input | Enable input; logic high enables converter operation, logic low forces shutdown mode with less than 2 µA quiescent current. |
| 9 | SW | output | Switch output connected to external inductor and internal power MOSFET drain. |
| 10 | PGND | power_in | Power ground connection; all power ground references must be connected to this pin. |
