TPS62A03ADRLR 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 | GND | power_in | Ground pin; connect the low side of the input and output capacitors to it to avoid ground potential shift. |
| 2 | SW | output | Switch pin connected to the internal FET switches and inductor terminal; connect the inductor of the output filter to this pin. |
| 3 | VIN | power_in | Power supply voltage pin with a 2.5V to 5.5V recommended input range. |
| 4 | EN | input | Device enable logic input where high enables the device and low puts it into shutdown; do not leave the pin floating. |
| 5 | FB | input | Feedback pin for the internal control loop; connect it to an external feedback divider referenced to 0.6V. |
| 6 | PG | output | Power-good open-drain output; the pullup resistor cannot be connected to any voltage higher than 5.5V, and if unused leave open or connect to GND. |
