ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings specific operating conditions in conjunction with board layout, the rated may cause permanent damage to the device. Exposure to any Absolute package thermal impedance, and other environmental factors. The junction Maximum Rating condition for extended periods may affect device temperature (TJ in °C) is calculated from ambient temperature (TA in °C) reliability and lifetime. and power dissipation (PD in Watts) according to the formula:
Note 2:
The LTC3307A is tested under pulsed load conditions such TJ = TA + (PD • θJA), where θJA (in °C/W) is the package thermal that TJ ≈ TA. The LTC3307AE is guaranteed to meet specifications from impedance. See High Temperature Considerations section for more 0°C to 85°C junction temperature. Specifications over the –40°C to details. 125°C operating junction temperature range are assured by design, The LTC3307A includes overtemperature protection that protects the characterization, and correlation with statistical process controls. The device during momentary overload conditions. Junction temperatures will LTC3307AI is guaranteed over the –40°C to 125°C operating junction exceed 150°C when overtemperature protection is engaged. Continuous temperature range. The LTC3307AH is guaranteed over the –40°C to operation above the specified maximum operating junction temperature 150°C operating junction temperature range. The LTC3307AMP is may impair device reliability. guaranteed over the –55°C to 150°C operating junction temperature range.
Note 3:
Supply current specification does not include switching currents. High junction temperatures degrade operating lifetimes; operating lifetime Actual supply currents will be higher. is derated for junction temperatures above 125°C. Note that the maximum ambient temperature consistent with these specifications is determined by Rev. 0 4 For more information www.analog.com Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Order Information Pin Configuration Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Typical Applications Package Description Typical Application Related Parts
