11. Application information
Capacitor CVCC buffers the IC supply voltage, which has to be supplied by external
means. Sense resistor RSENSE1 converts the current through the MOSFET S1 into a
voltage at pin PFCSENSE. The value of RSENSE1 denes the maximum primary peak
current in MOSFETS S1.
RS1 is added to prevent the soft start capacitor from being charged during normal
operation due to negative voltage spikes across the sense resistor.
Resistor RAUX1 is added to protect the IC from damage during lightning events.
