LSP5526-S8A from Diodes Incorporated, 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 | BS | power_out | Bootstrap pin that acts as the positive rail for the high-side switch gate driver; connect a 0.01uF capacitor between BS and SW. |
| 2 | VIN | power_in | Input supply pin that should be bypassed to GND with a low ESR capacitor placed close to the pin. |
| 3 | SW | output | Switch output pin that connects to the switching end of the inductor. |
| 4 | GND | power_in | Ground pin. |
| 5 | FB | input | Feedback input regulated to 0.925V; connect to the resistor divider between output and ground to set the output voltage. |
| 6 | COMP | passive | Compensation pin for the error amplifier; stability compensation network is connected here (RCOMP, CCOMP1, and CCOMP2 if a high ESR output capacitor is used). |
| 7 | EN | input | Enable input: above 2.7V turns the IC on, below 1.1V turns it off, and it should not be left open. |
| 8 | SS | input | Soft-start control input; a capacitor from SS to GND sets the soft-start period (0.1uF gives 15ms), and leaving SS unconnected disables soft-start. |
