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. THERMAL CHARACTERISTICS The exposed paddle must be soldered to the ground plane for the LFCSP package. This increases the reliability of the solder joints, maximizing the thermal capability of the package. Table 7. Thermal Resistance PackageType Airflow Velocity (m/sec) θJA1,2 θJC1,3 θJB1,4 Unit 48-Lead LFCSP 7 mm × 7 mm (CP-48-13) 0 25 2 14 °C/W 1.0 22 °C/W 2.5 20 °C/W 1 Per JEDEC 51-7, plus JEDEC 25-5 2S2P test board. 2 Per JEDEC JESD51-2 (still air) or JEDEC JESD51-6 (moving air). 3 Per MIL-STD-883, Method 1012.1. 4 Per JEDEC JESD51-8 (still air). Typical θJA is specified for a 4-layer printed circuit board (PCB) with a solid ground plane. As shown in Table 7, airflow increases heat dissipation, which reduces θJA. In addition, metal in direct contact with the package leads from metal traces, through holes, ground, and power planes reduces the θJA. ESD CAUTION |
