RT5762DHGH6F from Richtek Tech, 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 | FB | input | Output voltage sense input: the output is sensed at the FB pin through a resistive divider, with a feedback reference voltage of 0.6V typically. |
| 2 | GND | power_in | Power ground. |
| 3 | VIN | power_in | Power input with an input voltage range from 2.5V to 6V; input bypass capacitors connect directly to this pin and GND, and MLCC with capacitance higher than 10F is recommended. |
| 4 | SW | output | Switch node between the internal switch and the synchronous rectifier, connected to the inductor. |
| 5 | EN | input | Enable control input: logic high enables the device and connecting this pin to ground disables the device. |
| 6 | NC | unconnected | No internal connection for the RT5762C/D variant. |
