App note: How to prevent thermal issues with high output current DC to DC converters in portable applications

Tips and tricks from ON Semiconductors on how to optimize high output current switching regulators thermal dissipation. Link here (PDF)

As power demand in portable designs is more and more important, designers must optimize full system efficiency in order to save battery life and reduce power dissipation. Energy losses study allows knowing thermal stakes. Due to integration and miniaturization, junction temperature can increase significantly which could lead to bad application behaviors or in worst case to reduce components reliability.
