Smaller, smarter, and more powerful are market trends for low-power switched-mode power supply (SMPS) applications. Smaller requires the SMPS to have a more compact form factor – and, thus higher power density. Smarter requires intelligent system-to-system/system-to-human communication to ensure the systems

Measuring the resistance of something is a great deal more complicated if that resistance is very small. With bigger resistances, measurements can be as simple as connecting two leads between a digital multi-meter (DMM) and the device under test (DUT) and reading the number. With small resistances, the multitude

Thermal behavior is important to determining the lifetime performance of electronic system design and the power supply is a critical element in determining that behavior. Heat has a number of effects on a system. The most problematic at a system level is one of long-term reliability. High operating temperatures
