PL8310 from POWLICON, in a SOP-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 | BST | power_out | Boot-strap pin; connect a 0.1µF or greater capacitor between SW and BST to power the high-side gate driver. |
| 2 | SW | output | Power switching pin; connect this pin to the switching node of the inductor. |
| 3 | GND | power_in | Ground reference pin for the device; the input and output capacitor grounds and the R2 ground should connect directly to this pin. |
| 4 | VIN | power_in | Power input supplying the IC; supply with a 4.5V to 36V source and bypass to GND with a large capacitor plus at least 0.1µF ceramic placed close to VIN and GND. |
| 5 | FB | input | Feedback input sensing the output voltage through a resistor divider to ground; it is a sensitive node to keep away from SW and BST, and connect it directly to output when CS is floating or tied to output. |
| 6 | EN | input | Digital enable input that turns the regulator on when driven high and off when low, with an internal pull-up to VIN and a threshold of 1.1V without hysteresis. |
| 7 | LED | input | LED input connected to the negative terminal of an LED to indicate output status. |
| 8 | CS | input | Current sense input; connect a 10mΩ to 100mΩ resistor between this pin and GND to program the current limit, and its connection also sets the work mode. |
