This file type includes high resolution graphics and schematics. Capacitor-based charge pumps (or Q-pumps) generally aren’t useful for sourcing large amounts of current, but they work well in niche ...

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 ...

Catalyst Semiconductor has introduced a pair of very low noise, regulated output charge pumps that implement a 2MHz constant switching frequency, enabling the use of small 1F ceramic capacitors. The ...

Capacitor-based charge pumps (or Q-pumps) generally aren’t useful for sourcing large amounts of current, but they work well in niche micropower applications where space is at a premium. They work best ...
