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.
