The may cause permanent damage to the device. Exposure to any Absolute junction temperature (TJ in °C) is calculated from the ambient temperature Maximum Rating condition for extended periods may affect device (TA, in °C) and power dissipation (PD, in watts) according to the formula: reliability and lifetime. TJ = TA + (PD • θJA), Note 2: All currents into pins are positive; all voltages are referenced to where the package thermal impedance θJA = 92°C/W). GND unless otherwise noted. Note that the maximum ambient temperature consistent with these Note 3: The LTC4126E is tested under conditions such that T specifications is determined by specific operating conditions in J ≈ TA. The LTC4126E is guaranteed to meet performance specifications from conjunction with board layout, the rated package thermal resistance, and 0°C to 85°C junction temperature. Specifications over the –20°C to other environmental factors. 85°C operating junction temperature range are assured by design, Note 4: See DC/DC Converter in Operation section.
