Preliminary Data Sheet
Revision 1.19 – May 07, 2008
Thermal Management
The following heat sinks were used in the above thermal analysis:
ALPHA W35-15W (35mm x 35mm x15mm)
ALPHA LPD35-15B (35mm x 35mm x15mm)
The heat sinks are manufactured by:
Alpha Novatech, Inc. (www.alphanovatech.com)
473 Sapena Court, #12
Santa Clara, CA 95054
Phone: 408-567-8082
Notes:
1. Case temperature, TC, is measured at top center of case surface with device soldered to circuit board.
2. TA = TC - P×θCA, where TA is ambient temperature and P is power consumption.
3. TCMax = TJMax - P×θJC, where TJMax is maximum junction temperature (+125°C) and P is power consumption.
4. The preceding equations assume that the chip is mounted on a board with at least one signal and two power planes.
5. Values in the table were achieved with a JEDEC standard board: 114.5mm x 101.6mm x 1.6mm, 4 layers.
6. Values for an attached heat sink were achieved with a 35mm x 35mm x 15mm unit (see Thermal Management below), attached with a
0.1mm thickness of adhesive having a thermal conductivity of 1.3 W/mK.
