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 ...
Designed to deliver uniform flicker-free backlighting for LCD displays and keypads, the CAT3604 regulated charge pump achieves efficiencies of up to 93%. Each output channel is current regulated to ...
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 ...
