NOTES:

1. Auto-restart ON-time is a function of switching frequency programmed by t

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. I

typical specification under worst case application conditions (rectified 265 VAC) for no-load consumption calculations.

4. When the duty-cycle exceeds DC

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.
