ELECTRICAL CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS

V

Note 1 . Specifications are tested for production at T

temperature range are assured by design, characterization and correlation with Statistical Quality Controls (SQC).

Note 2. V

Note 3. Load regulation is measured at constant junction temperature, using pulse testing with a low ON time.

Note 4. Current limit is measured by pulsing a short time.

Note 5. In order to safely operate your system, V
