ADP1864 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 2.
Stresses above those listed under Absolute Maximum Ratings
Parameter Rating
may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any IN to GND −0.3 V to +16 V other conditions above those indicated in the operational CS, PGATE to GND −0.3 V to (V + 0.3 V) IN section of this specification is not implied. Exposure to absolute FB, COMP to GND −0.3 V to +6 V maximum rating conditions for extended periods may affect θ 2-Layer (SEMI Standard Board) 315°C/W JA device reliability. θ 4-Layer (JEDEC Standard Board) 186°C/W JA Operating Junction Temperature Range −40°C to +125°C Storage Temperature Range −65°C to +150°C
