range, otherwise specifications are at 25

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: Based on long-term current density limitations.

Note 3: The LTC3203/LTC3203-1/LTC3203B/LTC3203B-1 are 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.

Note 4: Output not in regulation (based on wafer sort):

Note 5: Proper conversion mode, 1.5x or 2x, has to be chosen based on
