Single-Cell Regulated Charge Pump Draws Low Quiescent Current

A charge pump (or Q pump) uses a flying-capacitor architecture to boost a single cell's voltage to a regulated 2.5V, yet operates at low quiescent current. This approach is a good fit for microcontroller applications where the load is usually in sleep mode and quiescent battery drain is more important than efficiency at higher loads. The two-stage design has efficiency in the 40 to 70% range—comparable to an LDO—yet consumes just microamps when the load is not active....More
