Data Sheet ADP5014 ABSOLUTE MAXIMUM RATINGS Table 3.
Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a AVIN to Ground −0.3 V to +6.5 V stress rating only; functional operation of the product at these PVIN1 to PGND1 −0.3 V to +6.5 V or any other conditions above those indicated in the operational PVIN2 to PGND2 −0.3 V to +6.5 V section of this specification is not implied. Operation beyond PVIN3 to PGND3 −0.3 V to +6.5 V the maximum operating conditions for extended periods may PVIN4 to PGND4 −0.3 V to +6.5 V affect product reliability. SW1 to PGND1 −0.3 V to +6.5 V
THERMAL RESISTANCE
SW2 to PGND2 −0.3 V to +6.5 V Thermal performance is directly linked to printed circuit board SW3 to PGND3 −0.3 V to +6.5 V (PCB) design and operating environment. Close attention to SW4 to PGND4 −0.3 V to +6.5 V PCB thermal design is required. PGND to Ground −0.3 V to + 0.3 V CFG1, CFG2 to Ground −0.3 V to +6.5 V
