AP4306AKTR-G1 from Diodes Incorporated, in a SOT-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 | VCTRL | input | Input pin of the voltage control loop, whose internal reference is 1.21 V (A version VREF 1.198 to 1.222 V at 25°C). |
| 2 | GND | power_in | Ground pin for the controller. |
| 3 | VOUT | output | Output pin that sinks current only; datasheet gives VOL of 100 mV at 10 mA sink and IOS of 27 mA typical (50 mA max) at 25°C. |
| 4 | ICTRL | input | Input pin of the current control loop; the datasheet gives an input current out of ICTRL at VSENSE of 18 µA typical at 25°C (A version). |
| 5 | VSENSE | input | Input pin of the current control loop, with the A version current-sense reference of 70 mV (63 to 77 mV over -40°C to +105°C). |
| 6 | VCC | power_in | Power supply pin; recommended operating supply range is 2.5 V to 18 V and the absolute maximum is 20 V. |
