Transformers can often provide an inexpensive solution for a variety of applications. The purpose of the transformer is to isolate the secondary side of the circuit from the primary power source, transfer power efficiently from the electrical source to the target load and protect users from hazards like electric sh

An effective method for filtering high-frequency power supply noise and cleanly sharing similar voltage supply rails (i.e. analog and digital rails for mixed-signal ICs) while preserving high-frequency isolation between the shared rails is the use of ferrite beads. A ferrite bead is a passive device that fi

In the third part of this series, we’ll see how Dr. Fred Lee’s analysis of current-mode control resulted in a high modulator gain, and also look at the consequences of this gain on current-loop predictions.
Current-Mode Control Circuit
Figure 1 shows a buck converter with peak current-mode control. T
