The Charge-Pump Option to LDO and Inductor-Based Regulators (.PDF Download)

    Feb. 29, 2016

    A charge pump is a type of switch-mode power-supply (SMPS) circuit that’s used as a dc-dc converter or regulator with appropriate feedback control.  The charge pump is often overlooked when considering a new design requiring these circuits. Because of its simplicity and other benefits, the charge pump may be a better choice over the use of a low-dropout (LDO) linear regulator or a switch-mode regulator using an inductor.  In your next design, you may want to consider this classic circuit and its advantages...
