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 ...
Requiring few external capacitors and no inductors, the TPS6050x charge pumps allow for a complete converter to be built in an area measuring just 0.155 in.2. With a quiescent current of 40 µA, the ...
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 ...
