Inductorless (Charge Pump) DC/DC Converters

Analog Devices’ family of charge pumps offers the widest selection of simple and compact inductorless dc-to-dc converter designs. These converters can be used to step-up, step-down, or invert an input voltage. By eliminating the inductor, these switched capacitor converters provide a small solution footprint and a simpler design. Furthermore, by incorporating spread spectrum technology on-chip, both input and output noise are significantly reduced.
