Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Reverse Output current has to be limited by the load to stay within absolute maximum ratings and thermal performance.
2. Minimum Pad.
3. 1 in square pad size, FR−4, 1 oz Cu.
4. Not subjected to production testing.
