AP3105VKTR-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 | GND | power_in | Signal ground that serves as the current return for the driver and control circuits. |
| 2 | FB | input | Feedback input connected directly to the opto-coupler, where the voltage sets the peak inductor current, a sustained voltage above 4.2V for about 32ms triggers protection, and a voltage below 1.55V stops the drive pulse. |
| 3 | CTRL | input | Latch trigger input that latches the IC off if the voltage falls below 0.5V or rises above 2.5V, may be left open if unused, and can use an NTC to GND for over-temperature protection, with the sourcing current limited below 5mA. |
| 4 | SENSE | input | Current sense input whose undershoot (which can reach about -0.3V at MOSFET turn-on) may damage the pin, so a small RC filter or series resistor is recommended. |
| 5 | VCC | power_in | Supply voltage input for the driver and control circuits, with UVLO turn-on at 15.5V and turn-off at 8.6V (typ) and a absolute maximum rating of 30V. |
| 6 | GATE | output | Gate driver output for the external power MOSFET, clamped at about 11V to 15V (13V typ). |
