1 All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.

2 Guaranteed by design, not tested in production.

3 If SYNC function is used, then f

SYNC must be greater than fCT, but less than 120% of fCT.

4 V

CS = (VCS+) – (VCS–).

5 Accuracy guaranteed by ISET INPUT, Programming Function Accuracy specification.

6 System current sense is active during shutdown.

7 Load current is supplied through SYS+ pin.
