NCP1601A Product details

Description

Pin Symbol Function 1 FB Feedback / Shutdown 2 Vcontrol Control 3 Ramp 4 CS Ramp Current Sense 5 Osc Oscillator / Synchronization 6 GND 7 Drv 8 VCC The IC ground Drive Output Supply Voltage Function This pin receives a current IFB which is proportional to the PFC circuit output voltage.The current is for the output regulation, output Overvoltage Protection (OVP), and output undervoltage protection (UVP).When IFB goes above 107% Iref, OVP is activated and the Drive Output is disable
