Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Rise and fall times are measured using 10% and 90% levels. Delay may cause permanent damage to the device. Exposure to any Absolute times are measured using 50% levels. Maximum Rating condition for extended periods may affect device
Note 4:
This IC includes overtemperature protection that is intended reliability and lifetime. to protect the device during momentary overload conditions. Junction
Note 2:
The LT8714E is guaranteed to meet performance specifications temperature will exceed 125°C when overtemperature protection is active. from 0°C to 125°C junction temperature. Specifications over the Continuous operation over the specified maximum operating junction –40°C to 125°C operating temperature range are assured by design, temperature may impair device reliability. characterization and correlation with statistical process controls. The

Do not apply a positive or negative voltage or current source to the LT8714I is guaranteed over the full –40°C to 125°C operating junction BG, TG, and INTVEE pins, otherwise permanent damage may occur. temperature range.
Note 6:
Negative FB current is defined as current flowing out of the FB pin. Positive FB current is defined as current flowing into the FB pin. 8714f For more information www.linear.com/LT8714 5 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Appendix Typical Applications Package Description Typical Application Related Parts
