TPS61251DSGT from Texas Instruments, in a WSON-8-EP(2x2). 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 | GND | power_in | Ground. |
| 2 | VOUT | power_out | Boost converter output. |
| 3 | FB | input | Voltage feedback pin. |
| 4 | ILIM | input | Adjustable average input current limit that can be connected to VIN for maximum limit or to GND for minimum limit. |
| 5 | PG | output | Output power good signal with open-drain output; logic 1 indicates good condition, logic 0 indicates failure. |
| 6 | EN | input | Enable input; logic 1 enables device, logic 0 disables device. |
| 7 | SW | output | Connection for inductor. |
| 8 | VIN | power_in | Supply voltage for power stage with recommended input range of 2.3 V to 6.0 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
