NOTES:
A. Auto-restart ON-time is a function of switching frequency programmed by tON × 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 LinkSwitch-3 operates in on-time extension mode.
E. This parameter is derived from characterization.
F. The switching frequency is programmable between 60 kHz to 85 kHz.
G. At light load tFB is reduced at 1.8 ms typical.
