LTC3633
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings impedance and other environmental factors. The junction temperature may cause permanent damage to the device. Exposure to any Absolute (TJ, in °C) is calculated from the ambient temperature (TA, in °C) and Maximum Rating condition for extended periods may affect device power dissipation (PD, in watts) according to the formula: reliability and lifetime. TJ = TA + (PD • θJA), where θJA (in °C/W) is the package thermal
Note 2:
The LTC3633 is tested under pulsed load conditions such that impedance. TJ ≈ TA. The LTC3633E is guaranteed to meet performance specifications
Note 3:
This IC includes overtemperature protection that is intended from 0°C to 85°C junction temperature. Specifications over the to protect the device during momentary overload conditions. Junction –40°C to 125°C operating junction temperature range are assured by temperature will exceed 125°C when overtemperature protection is active. design, characterization and correlation with statistical process controls. Continuous operation above the specified maximum operating junction The LTC3633I is guaranteed over the full –40°C to 125°C operating temperature may impair device reliability. junction temperature range. Note that the maximum ambient temperature
Note 4:
Dynamic supply current is higher due to the internal gate charge consistent with these specifications is determined by specific operating being delivered at the switching frequency. conditions in conjunction with board layout, the rated package thermal 3633fd 4 For more information www.linear.com/LTC3633 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Typical Applications Package Description Revision History Typical Application Related Parts
