**Texas Instruments** · DC-DC Converters · WSON-10-EP(3x3)

TPS61020DRCR from Texas Instruments, in a WSON-10-EP(3x3). 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 | Enable input (1/VBAT enabled, 0/GND disabled) |
| 2 | VOUT | power_out | Boost converter output |
| 3 | FB | input | Voltage feedback of adjustable versions |
| 4 | LBO | tri_state | Low battery comparator output (open drain) |
| 5 | GND | power_in | Control / logic ground |
| 6 | VBAT | power_in | Supply voltage |
| 7 | LBI | input | Low battery comparator input (comparator enabled with EN), may not be left floating, should be connected to GND or VBAT if comparator is not used |
| 8 | PS | input | Enable/disable power save mode (1/VBAT disabled, 0/GND enabled) |
| 9 | SW | output | Boost and rectifying switch input |
| 10 | PGND | power_in | Power ground |
| 11 | PowerPAD | power_in | Must be soldered to achieve appropriate power dissipation, should be connected to PGND |
