FP6151XR-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 | SW | output | Switch node output of the internal power MOSFET; the boost capacitor is connected between SW and BS, and absolute maximum Vsw is VIN +0.3V. |
| 2 | EN | input | Enable/UVLO input; driving it to ground shuts the device down, EN input high is 1.5V minimum and low is 0.4V maximum, and UVLO rising threshold is 3.9V to 4.5V. |
| 3 | COMP | output | Error amplifier output for compensation; the compensation network connected here sets the control loop response. |
| 4 | FB | input | Feedback input connected to the resistive divider from the output; the feedback voltage is 0.808V typical (0.788V to 0.828V), and it is a sensitive node to keep away from SW. |
| 5 | GND | power_in | Ground return for the device. |
| 6 | RT | input | Resistor connection that sets the oscillator frequency; RT = 200kΩ gives 400kHz to 600kHz switching frequency. |
| 7 | VIN | power_in | Supply voltage input with a recommended range of 4.5V to 36V (absolute maximum -0.3V to 42V). |
| 8 | BS | output | Bootstrap output that drives the high-side gate through a capacitor connected between BS and SW; absolute maximum VBS is Vsw +6V. |
| 9 | EP | power_in | Exposed pad on the package bottom that must be connected to ground. |
