Processor Power Supply Design
21103G/0—February 1999
Figure 4. Basic Synchronous Design
Another consideration is power dissipation in the lower
MOSFET (synchronous) or diode (asynchronous). As the output
voltage decreases the power dissipation in CR2 (Q2) increases.
The higher power dissipation may require using a different
package type or adding a heat sink to dissipate the additional
power.
To determine if the transistors or the diode need a heat sink use
the following equation:
P = I

Compare these calculations with the specifications of the
device used.
Switching Regulator
Layout
Each manufacturer has example layouts. Since the layout is
critical for stability and performance, AMD recommends
working closely with the manufacturer. For more information
on switching regulator layouts, refer to “Board Layout Boost
Power-Supply Performance” by Philip Rogers in the Nov. 5, 1998
issue of EDN (www.ednmag.com).
