LP6493BSOF from LOWPOWER, 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 | FB | input | Voltage feedback input with 0.6V reference, connected to the output divider (VOUT = 0.6V × (1 + RUP/RDN)) and also used for cable compensation. |
| 2 | CS | input | Output current sense pin; current limit trips when CS voltage exceeds 65mV (LP6493BSOF) per IOUT = VCS/RSEN. |
| 3 | GND | power_in | Ground. |
| 4 | VIN | power_in | Input supply voltage, 8V to 30V operating range (absolute maximum -0.3V to +36V). |
| 5 | SW | output | Switch node pin of the internal power MOSFETs (absolute maximum -0.3V to +36V), shorted with pin 6. |
| 6 | SW | output | Switch node pin of the internal power MOSFETs (absolute maximum -0.3V to +36V), shorted with pin 5. |
| 7 | GND | power_in | Power ground, shorted with pin 8. |
| 8 | GND | power_in | Power ground, shorted with pin 7. |
