NOTES:
1. I_DSS1 is the worst case OFF state leakage specification at 80% of BV_DSS and maximum operating junction temperature. I_DSS2 is a
typical specification under worst case application conditions (rectified 265 VAC) for no-load consumption calculations.
2. When the duty-cycle exceeds DC_MAX the LNK632DG operates in on-time extension mode.
3. This paramter is derived from characterization.
