LT1376- a linear circuit or a linear/digital circuit?

LT1376

Hi,
the step-down swtiching regulator LT1376 is to consider as a linear circuit or as a linear/digital circuit? The block schema in the datasheet as a SR flip-flop so I think that it has to be considered as linear/digital circuit.

Thank you
Enea

i would not call it either linear or digital circuit ,instead switching DC-DC circuit

the problem is that I'm making a reliability prediction analysis with the IEC TR 62380 standard and for integrated circuits it distinguishes between MOS, Bipolar and BiCMOS circuits and in this categories it is possible to choose between linear, digital, linear/digital,...
