NCP1200P40G

onsemi · AC-DC Controllers & Regulators · PDIP-8

NCP1200P40G from onsemi, in a PDIP-8. 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 Adj passive Adjusts the skip-cycle level, with a default skip mode level of 1.4 V (1.1 V to 1.6 V) and an internal output impedance of about 25 kΩ on this pin.
2 FB input Feedback input from the optocoupler that sets the peak current setpoint, with an internal pull-up resistor of 8.0 kΩ typical.
3 CS input Current sense input that routes the primary current through the leading edge blanking to the internal comparator, with a maximum internal current setpoint of 0.8 V to 1.0 V and a propagation delay of 160 ns maximum.
4 GND power_in IC ground reference.
5 Drv output Driver output to the external MOSFET gate, with source resistance of 40 Ω typical and sink resistance of 12 Ω typical.
6 VCC power_in Supplies the IC and connects to an external bulk capacitor of typically 10 µF, with a maximum rating of 16 V.
7 NC unconnected No internal connection; this pin is left unconnected to ensure adequate creepage distance.
8 HV power_in Connected to the high-voltage rail, this pin injects a constant current into the VCC bulk capacitor, with a maximum voltage of 450 V (VCC grounded) or 500 V (VCC decoupled with 10 µF) and a minimum operating voltage of 30 V.
