Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT3650E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls. The LT3650I specifications are
guaranteed over the full –40°C to 85°C temperature range. High junction
temperatures degrade operating lifetimes.
Note 3: V IN voltages below the start threshold are only supported if
(V BOOST – V SW ) > 2V.
