Note 1:
This is the V

current consumed when active, but not switching, so the gate-drive current is not included.
Note 2:
The reference output voltage (VREF) is measured with respect to FB. The difference between REF and FB is guaranteed to
be within these limits to ensure output voltage accuracy.
Note 3:
Specifications to -40
