Product details

Description

Pin Number Pin Name Pin Description 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 condi- tions.The pin becomes active when the PFC output achieves regulation in nominal operation, sourc- ing a current proportional to the feedback voltage, VFB.The PFCOK pin is bidirectional; it can be used to enable a downstream converter and can be used by the downstream converter to force the NCP1681 into S
