This formula can be used when the temperature of the exposed J C JC CC CC pad is known while the device is soldered down to a printed-circuit board (PCB). See the Applications Information section for details. The junction temperature must not exceed +150C. Note 2: Junction temperature T = T + ( x V x I ). This formula can be used when the ambient temperature of the PCB is J A JA CC CC known. The junction temperature must not exceed +150C. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Note 4: T is the temperature on the exposed pad of the package. T is the ambient temperature of the device and PCB. C A Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.
