1. The AAT2610 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and correla-
tion with statistical process controls.
2. The Step-Up converter operates in startup mode until this voltage is reached. Do not apply full load current during startup.
