ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings these specifications is determined by specific operating conditions in may cause permanent damage to the device. Exposure to any Absolute conjunction with board layout, the rated package thermal impedance, Maximum Rating condition for extended periods may affect device and other environmental factors. The junction temperature (TJ in °C) is reliability and lifetime. calculated from ambient temperature (TA in °C) and power dissipation (PD
Note 2:
The LTC3308A is tested under pulsed load conditions such in Watts) according to the formula: that TJ ≈ TA. The LTC3308AE is guaranteed to meet specifications from TJ = TA + (PD • θJA), where θJA (in °C/W) is the package thermal 0°C to 85°C junction temperature. Specifications over the –40°C to impedance. See High Temperature Considerations section for more 125°C operating junction temperature range are assured by design, details. characterization, and correlation with statistical process controls. The The LTC3308A includes overtemperature protection that protects the LTC3308AI is guaranteed over the –40°C to 125°C operating junction device during momentary overload conditions. Junction temperatures will temperature range. The LTC3308AJ and LTC3308AH are guaranteed exceed 150°C when overtemperature protection is engaged. Continuous over the –40°C to 150°C operating junction temperature range. The operation above the specified maximum operating junction temperature LTC3308AMP is guaranteed over the –55°C to 150°C operating junction may impair device reliability. temperature range. High junction temperatures degrade operating
