AP3441SHE-7B from Diodes Incorporated, in a DFN2020-8-EP. Symbol and footprint are the ones used on Adom board designs (KiCad official libraries); the 3D model is Adom-generated from Diodes' U-DFN2020-8 (Type E) drawing with the KiCad 3D model generator. Pin functions are extracted from the manufacturer datasheet with page references.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Feedback voltage to internal error amplifier, the threshold voltage is 0.6V. [datasheet p.2] |
| 2 | PG | open_collector | Power good indicator, open drain output. PG is pulled up to VIN when the output voltage is within 20% of the regulation level, otherwise it is low. [datasheet p.2] |
| 3 | VIN | power_in | Bias supply. Chip main power supply pin [datasheet p.2]; input voltage 2.7 V to 5.5 V. [datasheet p.1] |
| 4 | PGND | power_in | Power ground pin. [datasheet p.2] |
| 5 | NC | no_connect | No connection. [datasheet p.2] |
| 6 | LX | power_out | The drains of the internal main and synchronous power MOSFET. [datasheet p.2] |
| 7 | EN | input | Enable control input. Force this pin voltage above 1.5V enables the chip, and below 0.4V shuts down the device. [datasheet p.2] |
| 8 | SGND | power_in | Signal ground pin. [datasheet p.2] |
| 9 | EP | passive | Exposed Pad: exposed metal pad on the underside of the package without any electrical connection to internal circuit; connect it to the PC board ground plane to improve heat dissipation. [datasheet p.2] |
