NOTE:

7. Specifications at -40°C and +105°C are guaranteed by +25°C test with margin limits.

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. Limits established by characterization and are not production tested.

Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 2

and “Typical Application” on page 3. 17V < VPWR < 100V, CVSW = 1µF, IVSW = -3mA, VSW Enabled, TA = -40°C to +105°C (Note 7), Typical values are at

TA = +25°C. (Continued)
