For every 10 degrees in junction temperature rise, the chances of your IC 
failing *doubles*. With megatrends like increasing power levels, shrinking 
PCB area, and smaller and smaller package sizes, how can you protect your 
design against heat and ensure long-term system reliability?

In this thorough training, learn about how to optimize your DC/DC switching 
regulator design for thermal performance. The LM73605 [1]/6 [2] and LM76002 
[3]/3 [4] synchronous buck converters serve as the example devices. Topics 
discussed in this video include:

 * Packaging options and what to look for to maximize thermal performance
 * Thermal resistance metrics from the datasheet and what they mean
 * Calculating PCB area requirements for heat sinking
