NOTES:

8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established

by characterization and are not production tested.

9. At minimum VIN of 4.5V, the maximum output is limited by the VOUT specifications. Also at maximum VIN of 26V, the minimum

VOUT is 28V but minimum VOUT can be lower at lower VIN. In general, the VIN and VOUT relationship is bounded by DMAX and

DMIN.
