| Part Number | NCP1680 |
| Manufacturer | ON Semiconductor (https://www.onsemi.com/) |
| Description | Table 1. PIN DESCRIPTIONS Pin Number Pin Name Function 1 FAULT Combined OVP/OTP fault pin. 2 PFCOK The PFCOK pin is held low when the PFC output voltage is out of regulation and during fault conditions. The pin becomes active when the PFC output achieves regulation in nominal operation, sourcing a current proportional to the feedback voltage, VFB. . |
