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) PARAMETER SYMBOL TEST CONDITIONS MIN (Note 6)TYP MAX (Note 6)UNITS |
