TPS564257DRLR from Texas Instruments, in a SOT-563. 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 | Input supply voltage pin supporting 3-V to 17-V operation with input decoupling capacitors connected between VIN and GND. |
| 2 | SW | power_out | Switch node for connection to output inductor in synchronous buck converter topology. |
| 3 | GND | power_in | Ground pin for controller circuit and internal circuitry. |
| 4 | PG | tri_state | Open-drain power-good indicator with 0.4-V output low-level voltage at 4-mA sink current. |
| 5 | EN | input | Enable control input with 1.19-V rising threshold for converter enable. |
| 6 | FB | input | Feedback input for connection to output voltage via resistor divider with 600-mV reference. |
