PAM2423AECADJR from Diodes Incorporated, in a ESOP-8. 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 | PGND | power_in | Power ground. |
| 2 | IN | power_in | Supply input; operating input voltage range is 2.7V to 5.5V. |
| 3 | EN | input | Enable control: logic high enables the IC, logic low disables it, and when unused it must be connected to IN (do not leave floating). |
| 4 | COMP | passive | Error amplifier compensation node for external loop compensation. |
| 5 | AGND | power_in | Analog ground. |
| 6 | FB | input | Feedback input; connect to a resistor divider from the output to set the output voltage, FB is regulated to 1.262V. |
| 7 | SS | passive | Soft-start control input; connect a capacitor to ground to set soft-start duration, discharged to ground in shutdown, may be left unconnected if soft start is not desired. |
| 8 | SW | output | Switch output; connect to the inductor and the Schottky diode, and minimize the PCB trace path between this pin and the input bypass capacitor to reduce EMI. |
| 9 | Exposed PAD | power_in | Exposed pad connected to ground. |
