TPS73801-SEP: same die as TPS73801

Art,

Unfortunately we can’t share information specific to a device. Typically there are differences between space and commercial devices. These differences can be in form of process, layout, design changes. These are done to improve radiation performance of space device. Please note that radiation performance for commercial device can be significantly worse compared to space qualified device even though electrical performance is identical. In addition there are several factors on commercial device that makes it risky for space applications. Some of important factors:

• No single controlled baseline: Translates to high variability of radiation performance
• Mostly use copper bond-wire: May not be reliable for space environment
• No testing for radiation at lot level: High risk of getting devices that have poor radiation level
