NCP1653ADR2G

onsemi · AC-DC Controllers And Regulators · SOP-8

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.
