XRP7664IDTR-F from MaxLinear, in a SOIC-8-150mil. 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 | passive | Bootstrap pin; connect a 0.01µF or greater bootstrap capacitor between BS and SW to drive the internal high-side power MOSFET. |
| 2 | IN | power_in | Power input pin, operating from 4.50V to 18V (absolute maximum VIN is 20V), with a capacitor between IN and GND to keep the input voltage constant. |
| 3 | SW | power_out | Power switch output pin connected to the inductor and the bootstrap capacitor, with a switch node voltage rating of 21V absolute maximum. |
| 4 | GND | power_in | Ground signal pin. |
| 5 | FB | input | Feedback pin set by an external resistor divider; overvoltage protection triggers above 1.1V and the oscillator frequency is lowered when the feedback voltage drops below 0.3V. |
| 6 | COMP | passive | Output of the transconductance error amplifier and input to the current comparator, compensated by an RC network connected from this pin to GND. |
| 7 | EN | input | Control input; forcing it above 2.7V enables the IC and below 0.75V shuts it down, and it may be pulled up to VIN through a 100kΩ resistor for automatic startup. |
| 8 | SS | passive | Soft-start control input; a capacitor from SS to GND sets the soft-start period (0.1µF gives 15ms), and leaving SS unconnected disables soft-start. |
