Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
Supply current is the total current for both drivers.
Note 3:
Only the LTC1693-3 has a PHASE pin.
Note 4:
All AC timing specificatons are guaranteed by design and are not
production tested.
Note 5:
Only applies to the LTC1693-1 and LTC1693-2.
