NOTES:

1. I

DSS1 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.

2. When the duty cycle exceeds DC

MAX the LinkSwitch-CV operates in on-time extension mode.

3. This parameter is derived from characterization.
