ADP2443 Data Sheet ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCE Table 2. Parameter Rating
Thermal performance is directly linked to printed circuit board PVIN, EN, PGOOD, RAMP −0.3 V to +40 V (PCB) design and operating environment. Careful attention to SW −1 V to +40 V PCB thermal design is required. BST VSW + 6 V
Table 3. Thermal Resistance
FB, SS, COMP, RT/SYNC −0.3 V to +6 V
Package Type θJA θJC Unit
VREG −0.3 V to +6 V CP-24-121 42.6 6.8 °C/W PGND to GND −0.3 V to +0.3 V Operating Junction Temperature Range −40°C to +125°C 1 Thermal impedance simulated value is based on a 4-layer, JEDEC standard board. Storage Temperature Range −65°C to +150°C Soldering Conditions JEDEC J-STD-020
ESD CAUTION
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.
