NCP1653ADR2G from onsemi, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Feedback/Shutdown pin receives feedback current IFB proportional to output voltage for regulation and protection; overvoltage protection triggers at IFB > 107% Iref and shutdown at IFB < 8% Iref. |
| 2 | Vcontrol | input | Control Voltage/Soft-Start pin voltage controls input impedance and power factor; external capacitor limits bandwidth typically below 20 Hz for unity power factor. |
| 3 | In | input | Input Voltage Sense pin sinks current Ivac proportional to RMS input voltage Vac for overpower limitation (when IS×Ivac > 3 nA²) and PFC duty cycle modulation. |
| 4 | CS | input | Input Current Sense pin monitors inductor current through external sense resistor RCS; overcurrent protection activates when sensed current IS exceeds 200 µA. |
| 5 | VM | output | Multiplier Voltage output provides voltage for PFC duty cycle modulation; external resistor RM sets input impedance and capacitor CM enables average current-mode operation. |
| 6 | GND | power_in | IC Ground connection. |
| 7 | Drv | output | Drive Output provides gate drive signal to external MOSFET with ±1.5 A peak current capability and typical rise/fall times of 88/61.5 ns. |
| 8 | VCC | power_in | Positive supply voltage with operating range 8.75 V to 18 V after startup; 13.25 V startup threshold with 4.55 V hysteresis and 18 V internal ESD protection. |
