Note 1:
Stresses beyond those listed under Absolute Maximum Ratings The LTM4608AI is guaranteed over the –40°C to 125°C internal operating may cause permanent damage to the device. Exposure to any Absolute temperature range and the LTM4608AMP is tested and guaranteed over Maximum Rating condition for extended periods may affect device the full –55°C to 125°C internal operating temperature range. Note that reliability and lifetime. the maximum ambient temperature consistent with these specifications
Note 2:
The LTM4608A is tested under pulsed load conditions such that is determined by specific operating conditions in conjunction with board T layout, the rated package thermal impedance and other environmental J ≈ TA. The LTM4608AE is guaranteed to meet specifications from 0°C to 125°C internal temperature. Specifications over the –40°C to factors. 125°C internal operating temperature range are assured by design,
