# RT5760CHGH6F

**Richtek Tech** · DC-DC Converters · SOT-563

RT5760CHGH6F 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 | Feedback voltage input that connects to the midpoint of the external feedback divider, regulating FB to the typical 0.6V reference. |
| 2 | GND | power_in | Signal and power ground; the bottom feedback resistor should be placed as close as possible to this pin. |
| 3 | VIN | power_in | Power input with a 2.5V to 6V input voltage range; input capacitors should connect directly to this pin and GND, with MLCC capacitance higher than 10µF recommended. |
| 4 | SW | power_out | Switch node of the internal power switches that connects to the inductor. |
| 5 | EN | input | Enable control input: logic high enables the device, GND disables it, and it must not be left floating. |
| 6 | NC | unconnected | No internal connection on the RT5760C/D variant; pin 6 is PG (power good) only on the RT5760A/B. |
