Capacitive charge-pump circuits are used in many applications. And though these circuits appear deceptively simple, engineers working on them need a thorough understanding of how they function. By ...

What is a charge pump? A charge pump provides dc-dc voltage conversion using a switch network to charge and discharge two or more capacitors. The basic charge pump switch network toggles between ...

Auxiliary power of 3.3V is replacing the 5V auxiliary power that “silver boxes” supply in most computer systems, but some circuits still require a 5V supply. Such systems impose the messy task of ...

Switching regulators are a popular choice for many power conversion supplies due to their size, output flexibility and efficiency advantages. Conversion efficacy of these supplies can now attain 98% ...
