RS6651YTH from Jiangsu RUNIC 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 | SW | input | Boost switch node; connect this node to one terminal of the power inductor (datasheet classifies the pin as I). Absolute maximum voltage on SW is -0.3 V to 6 V. |
| 2 | GND | power_in | Ground; the datasheet uses the GND pin as the reference for all voltages and as the star-connection point for grounds. |
| 3 | EN | input | Enable input; logic high (VIH min 1.4 V) enables the device and logic low (VIL max 0.4 V) disables it and puts it into shutdown mode. |
| 4 | FB | input | Voltage feedback input for the adjustable output voltage, regulated to a typical 500 mV (VFB range 480 mV to 510 mV). |
| 5 | VOUT | power_out | Boost converter output; place a storage capacitor close to this pin. The maximum recommended output voltage is 5.5 V. |
| 6 | VCC | power_in | Supply voltage input; recommended input supply range is 2.2 V to 4.5 V. |
