AP3441LSHE-7B from Diodes Incorporated, in a DFN-8-EP(2x2). 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 input to the internal error amplifier, with a threshold voltage of 0.6V. |
| 2 | PG | output | Open-drain power good indicator that is pulled up to VIN when the output is within 20% of regulation and is otherwise low. |
| 3 | VIN | power_in | Bias and main power supply pin, specified for 2.7V to 5.5V input. |
| 4 | PGND | power_in | Power ground pin for the internal power MOSFETs. |
| 5 | NC | unconnected | No internal connection. |
| 6 | LX | output | Connected to the drains of the internal main and synchronous power MOSFETs, forming the switching node. |
| 7 | EN | input | Enable control input that enables the chip above 1.5V and shuts the device down below 0.4V. |
| 8 | SGND | power_in | Signal ground pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
