NOTES:
A. Auto-restart on-time is a function of switching frequency programmed by tonx IFB and minimum frequency in CC mode.
B. 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.
C. 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.
D. When the duty cycle exceeds DCMAX the LYTSwitch-2 operates in on-time extension mode.
E. This parameter is derived from characterization.
