See Power Application Report. Table 7-1. Thermal Resistance Characteristics (PBGA Package) [ZUT] NO. °C/W(1) AIR FLOW (m/s)(2) 1 R Θ JC Junction-to-case 2 R Θ JB Junction-to-board 3 4 R Θ JA Junction-to-free air 5 7 8 PsiJT Junction-to-package top 9 11 12 PsiJB Junction-to-board 13 (1) The junction-to-case measurement was conducted in a JEDEC defined 1S0P system. Other measurements were conducted in a JEDEC defined 1S2P system and will change based on environment as well as application. For more information, see these three EIA/JEDEC standards: • EIA/JESD51-2, Integrated Circuits Thermal Test Method Environment Conditions - Natural Convection (Still Air) • EIA/JESD51-3, Low Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages • JESD51-7, High Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages . (2) m/s = meters per second The following packaging information and addendum reflect the most current data available for the designated device(s).
