These ICs work together in an active clamp flyback converter topology:
...
Lots of design examples are provided in the ‘design examples’ of the InnoSwitch page:
...
The DCM mode of operation will be used in order to decrease the size of the transformer. An example can be found here:
...
For DCM, tHLDLis a function of fet capacitance and leakage + magnetizing inductance of transformer
...
If constant current regulation is not required, the ISENSE pin must be tied to SECONDARY GROUND pin
