1 CS3 is an alternative output current reading that is calculated by the CS1 reading (representing input current), duty cycle, and main transformer turn ratio.

2 Endurance is qualified as per JEDEC Standard 22, Method A117, and is measured at −40°C, +25°C, +85°C, and +125°C.

3 Retention lifetime equivalent at junction temperature as per JEDEC Standard 22, Method A117.
