RT5752AHGJ5 from Richtek Tech, in a TSOT-23-5. 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 control input: a logic-high level enables the device and a ground connection disables it. |
| 2 | GND | power_in | Power ground for the converter. |
| 3 | SW | output | Switch node between the internal switch and the synchronous rectifier, connected to the inductor. |
| 4 | VIN | power_in | Power input with a range of 2.5V to 6V; bypass capacitors connect directly to this pin and the GND pins, and MLCC capacitance higher than 10µF is recommended. |
| 5 | FB | input | Output voltage sense input, connected through a resistive divider; the feedback reference voltage is 0.6V typically. |
