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 ...

Charge pumps, also known as inductorless DC/DC converters, are a special class of switching DC/DC converters that use capacitors as energy storage elements. When compared to “inductive” switching ...

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 ...
