Regulated Buck-Boost Charge Pumps

Analog Devices’ family of regulated buck/boost charge pumps accept input voltages above, equal to or below the output voltage and can be used to step-up or step-down an input voltage to a regulated output voltage. By eliminating the inductor, these switched capacitor converters offer alternatives to switching regulator topologies, providing a small solution footprint and a simple design. Key features include low quiescent current, multimode operation with automatic mode switching to maintain regulation, I_out up to 500mA, low noise constant frequency operation, Burst Mode^® operation, overtemperature, fault and short-circuit protection.
