Efficiency vs Load Current Vbst = 3.3V
100% 1000 90% 80% 100 LTC3100 70% Vin=1.2V
ELECTRICAL CHARACTERISTICS
60% 10 Vin=2.4V
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Current measurements are made when the output is not switching. may cause permanent damage to the device. Exposure to any Absolute Vin=3.0V 50%
Note 5:
This IC includes overtemperature protection that is intended Maximum Rating condition for extended periods may affect device to protect the device during momentary overload conditions. Junction reliability and lifetime. temperature will exceed 125°C when overtemperature protection is active. PL, Vin=1.2V
Efficiency(%) Note 2:
The LTC3100E is guaranteed to meet per 40% formance specifications Continuous operation above the specified maximum operating junction 1
Power Loss (mW)
from 0°C to 85°C. Specifications over –40°C to 85°C operating temperature may result in device degradation or failure. PL, Vin=2.4V temperature range are assured by design, characterization and correlation 30%
Note 6:
Failure to solder the exposed backside of the package to the PC with statistical process controls. board ground plane will result in a thermal resistance much higher than PL, Vin=3.0V
Note 3:
Specification is guaranteed by design and not 100% tested in 68°C/W. 20% 0.1 production. 10%
