This formula can be used when the temperature of the J C JC CC CC exposed pad is known while the device is soldered down to a PCB. See the Applications Information section for details. The junction temperature must not exceed +150NC. Note 2: Junction temperature T = T + (B 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 +150NC. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four- layer board.
