Note 3: Measured from point at which VNEG crosses –5V to point at which

C2– starts switching.

Note 4: The LTC3450E is guaranteed to meet performance specifications

from 0°C to 70°C. Specifications over the – 40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls.
