Data Sheet ADP2360 ABSOLUTE MAXIMUM RATINGS Table 2. THERMAL RESISTANCE Parameter Rating
θJA is specified for the worst case conditions, that is, a device VIN, EN, PG, to AGND, PGND −0.3 V to +61 V soldered in a circuit board for surface-mount packages. FB to AGND, PGND −0.3 V to +5.5 V For additional information on thermal resistance, refer to SW to AGND, PGND −0.3 V to VIN + 0.3 V Application Note AN-000, Thermal Characteristics of IC ITH, SS to AGND, PGND −0.3 V to +4 V Assembly. Operating Junction Temperature Range −40°C to +125°C Storage Temperature Range –65°C to +150°C

Stresses at or above those listed under Absolute Maximum 8-Lead LFCSP 62.7 33.60 °C/W Ratings may cause permanent damage to the product. This is a θJA and ΨJB and are modeled using a standard 4-layer JEDEC printed stress rating only; functional operation of the product at these circuit board (PCB) (2S2P) with the exposed pad soldered to or any other conditions above those indicated in the operational the board with a 2 × 2 array of thermal vias and still air. section of this specification is not implied.
