Data Sheet ADP5138 ABSOLUTE MAXIMUM RATINGS Table 4. THERMAL RESISTANCE Parameter Rating
Thermal performance is directly linked to printed circuit board PVIN1, PVIN2, PVIN3, PVIN4, PVIN5, AVIN, −0.3 V to +6 V (PCB) design and operating environment. VOUT5 Careful attention to PCB thermal design is required. SW1, SW2, SW3, SW4 −0.3 V to +6 V FB1, FB2, FB3, FB4, FB5, EN1, EN2, EN3, EN4, −0.3 V to +6 V

PGND1, PGND2, PGND3, PGND4 to GND −0.3 V to +0.3 V CP-28-5 32.6 1.4 °C/W Operating Temperature Range (Junction) −40°C to +125°C Storage Temperature Range −65°C to +150°C 1 θJA is measured using natural convection on a JEDEC 4-layer board with the Soldering Conditions JEDEC J-STD-020 exposed pad soldered to the PCB and with thermal vias. Electrostatic Discharge (ESD) Human Body Model 2000 V
ESD CAUTION
Charged Device Model 500 V Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
