Note 6: This IC includes over-temperature protection that is intended  
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.  
to protect the device during momentary overload conditions. Junction  
temperature exceeds 125°C when over-temperature protection is active.  
Continuous operation above the specified maximum operating junction  
temperature may impair device reliability.  
Note 2: Current into a pin is positive and current out of a pin is negative.  
Note 7: The LTC3569E is guaranteed to meet specified performance 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. The LTC3569I is guaranteed to meet specified  
performance over the full –40°C to 85°C operating temperature range.  
All voltages referenced to SGND.  
Note 3: Dynamic supply current is higher due to the internal gate charge  
being delivered at the switching frequency.  
Note 4: Specification is guaranteed by design and not 100% tested in  
production.  
Note 5: Switch on-resistance verified by correlation to wafer level  
measurements.
