AMCC Proprietary
Revision 1.09 - August 21, 2007
Preliminary Data Sheet
Thermal Management
The following heat sink was used in the above thermal analysis:
26.92mm x 27mm x 11.43mm
The heat sink is manufactured by:
Aavid Thermalloy, P/N 62925
Table 8. Package Thermal Specifications
The PPC405EX is designed to operate within a case temperature range TC defined in “Recommended DC Operating
Conditions” on page 47. Thermal resistance values for the EPBGA packages in a convection environment are as follows:

Notes:
1. Values in the table are achieved with the following JEDEC standard board: 114.5mm x 101.6mm x 1.6mm, 4 layers.
2. For a chip mounted on a card with at least one signal and two power planes, the following relationships exist:
a. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
b. TA = TC – PxθCA, where TA is ambient temperature and P is power consumption.
c. TCMax = TJMax – PxθJC, where TJMax is maximum junction temperature and P is power consumption.
