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 1.3W/mK.  
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
