RT6253BHGJ6F from Richtek Tech, in a TSOT-23-6. 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 | Power ground for the converter. |
| 2 | SW | output | Switch node between the internal switch and the synchronous rectifier; connect this pin to the inductor and bootstrap capacitor. |
| 3 | VIN | power_in | Power input with an input voltage range of 4.5V to 17V; connect input bypass capacitors directly to this pin and the GND pins, with MLCC capacitance above 20µF recommended. |
| 4 | FB | input | Feedback voltage input; connect to the midpoint of the external feedback resistive divider, and the device regulates the FB voltage at the feedback reference voltage. |
| 5 | EN | input | Enable control input; a logic-high voltage enables the device and connecting this pin to GND disables it. |
| 6 | BOOT | passive | Bootstrap capacitor connection node supplying the high-side gate driver; connect a 0.1µF ceramic capacitor between this pin and the SW pin. |
