NCP1203P60G 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 | Sets the level at which skip-cycle operation takes place (recommended operation between 400 mV and 1.3 V), and shorting it to ground permanently disables skip-cycle; it has an internal output impedance of 22 kΩ (typ). |
| 2 | FB | input | Peak current setpoint input connected to the optocoupler; skip cycle occurs when FB falls below the Pin 1 (Adj) level, with an internal pull-up resistor of 20 kΩ (typ). |
| 3 | CS | input | Current sense input that routes the primary current to the internal comparator via the leading edge blanking, with a maximum internal current setpoint of 0.85 V to 1.0 V (0.92 V typ). |
| 4 | GND | power_in | The IC ground reference for all internal circuitry. |
| 5 | Drv | output | Driver output to the external MOSFET gate, with rise and fall times of 67 ns and 28 ns (typ) at a 1.0 nF load. |
| 6 | VCC | power_in | Supplies the IC and is connected to an external bulk capacitor of typically 22 µF; the turn-on threshold is 12.2 V to 14 V, the minimum operating voltage after turn-on is 7.2 V to 8.4 V, and VCC must be kept below the 16 V maximum rating. |
| 7 | NC | unconnected | Unconnected pin that ensures adequate creepage distance. |
| 8 | HV | power_in | Connected to the high-voltage rail, it injects a constant current (6.0 mA typ at VCC = 10 V) into the VCC capacitor during startup; the maximum voltage on this pin is 500 V with VCC decoupled by 10 µF. |
