Pin Symbol Name Function 1 GND Ground . 2 Vin Multiplier This pin provides a voltage VM for the PFC duty cycle modulation. The input impedance of the Voltage PFC circuits is proportional to the resistor RM externally connected to this pin. The device operates in average current mode if an external capacitor CM is connected to the pin. Otherwise, it operates in peak current mode. 3 CS Current Sense This pin sources a current ICS which is proportional to the inductor current IL. The sense Input current ICS is for overcurrent protection (OCP), overpower limitation (OPL) and PFC duty cycle modulation. When ICS goes above 200 mA, OCP is activated and the Drive Output is disabled.
