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 ...
Maxim introduced the MAX1578/MAX1579, the first complete LCD bias and white-LED power supplies with only one inductor and no charge-pump diode. Four regulated outputs supply all the voltages required ...
Cost, size, resistance, and current capability drive the choice of inductor for most stepdown dc-dc switching converters. Many such applications specify the inductor value shown in the switching ...
