NOTES:  
1. Auto-restart ON-time is a function of switching frequency programmed by tonx IFB and minimum frequency in CC mode.  
2. The current limit threshold is compensated to cancel the effect of current limit delay. As a result the output current stays constant  
across the input line range.  
3. IDSS1 is the worst case OFF state leakage specification at 80% of BVDSS and maximum operating junction temperature. IDSS2 is a  
typical specification under worst case application conditions (rectified 265 VAC) for no-load consumption calculations.  
4. When the duty-cycle exceeds DCMAX the LinkSwitch-II operates in on-time extension mode.  
5. This parameter is derived from characterization.  
6. Mechanical stress induced during the assembly may cause shift in this parameter. This shift has no impact on the ability of  
LinkSwitch-II to meet 10% in mass production given the design follows recommendation in AN-44 and good manufacturing practice  
7. The switching frequency is programmable between 60 kHz and 85 kHz.
