NOTES:
6. 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.
7. Care must be taken not to exceed the phase node max voltage rating.
Electrical Specifications VIN = 4.5V to 16V, unless otherwise noted. Typical values are at TJ = +25°C. Boldface limits apply across the
junction temperature range, -40°C to +125°C. (Continued)
