Instead, you’ll have to build one out of inductors. After all, a transformer is just two inductors (the primary and the secondary). Due to coupling, changes in the magnetic field of the primary ...

Figure 1 : Generic boost (a) and buck (b) Inductor-based Switching Regulators On the other hand, inductorless SRs (figure 2) exploit only one or two small and cheap ceramic capacitors (flying ...
