NCP1200D60R2G from onsemi, in a SOIC-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 | input | Adjusts the skip-cycle level; the default skip mode level is 1.4 V (1.1 V to 1.6 V) and pin 1 has a 25 kΩ internal output impedance. |
| 2 | FB | input | Sets the peak current setpoint through an optocoupler connection, with an internal pullup resistor of 8.0 kΩ typical. |
| 3 | CS | input | Senses the primary current and routes it through the leading edge blanking to the internal comparator, with a maximum internal current setpoint of 0.9 V typical (0.8 V to 1.0 V). |
| 4 | GND | power_in | The IC ground pin. |
| 5 | Drv | output | Drives the external MOSFET gate, with 67 ns typical rise time and 28 ns typical fall time at a 1 nF load. |
| 6 | VCC | power_in | Supplies the IC and is connected to an external bulk capacitor of typically 10 µF; the current source turns off at 11.4 V typical and on at 9.8 V typical. |
| 7 | NC | unconnected | No connection; this un-connected pin ensures adequate creepage distance. |
| 8 | HV | power_in | Connected to the high-voltage rail, it injects a constant current into the VCC bulk capacitor, with a minimum operating voltage of 30 V. |
