FP6188XR-G1 from Advanced Analog Technology, in a SOP-8-EP. 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: a flying bootstrap capacitor connected between SW and BS supplies the high-side n-channel MOSFET gate-drive voltage, and the capacitor is charged from the internal regulator while SW is low. |
| 2 | IN | power_in | Supply voltage input: the recommended operating range is 4.5V to 23V, with an absolute maximum of 24V (VIN). |
| 3 | SW | output | Switch node connecting the internal power MOSFETs to the external inductor; absolute maximum range is -1V to VIN+0.3V. |
| 4 | GND | power_in | Ground pin for the device, which must be connected to system ground. |
| 5 | FB | input | Feedback input that senses the output through a resistive divider; the feedback voltage is 0.923V typical (0.900V to 0.946V), and the feedback overvoltage threshold is 1.1V. |
| 6 | COMP | output | Error amplifier output where a compensation network is connected to stabilize the current-mode control loop. |
| 7 | EN | input | Enable/UVLO input: the rising threshold is 1.5V typical with 200mV hysteresis, and driving it to ground shuts the device down. |
| 8 | SS | output | Soft-start pin that sets the startup ramp, with a soft-start current of 6µA at VSS=0V. |
| 9 | EP | power_in | Exposed pad that must be connected to ground; the SOP-8L (EP) thermal resistance junction-to-ambient is 83°C/W. |
