6 FAQs about [Charge pump energy storage inductor]

What is the difference between charge pump and inductive DC-DC converter?

If they use inductors as energy storage elements, they are known as inductive DC-DC converters. Accordingly, if they use only capacitors to store and transfer charge, they belong in the category of switched-capacitor converters. Charge pumps belong to the second category as they consist of capacitors and switches.

Is a charge pump better than an inductive converter?

While perhaps not as eficient as an inductive-based converter, a charge pump provides ease of use, small solution size and ruggedness not found in the inductive alternative. Charge-pump devices come in boost, buck and inverting flavors (just like their magnetic brethren) without the cost and inductor printed circuit board (PCB) area requirements.

How does a charge pump converter work?

Through the use of a few small and inexpensive external capacitors, a charge-pump converter can convert one DC voltage just like a magnetic DC/DC converter.

What is the difference between a charge pump and an inductive solution?

Figure 1. Example of a Charge Pump (12mm2) Versus an Inductive Solution (29mm2): VIN = 3.0V to 4.5V and vOUT = 5V at 150mA Charge-pump DC/DC devices enable you to generate different output voltages (boost/buck/inverted) from a given input voltage.

Are charge pumps a DC/DC converter?

Charge pumps can provide a DC/DC converter solution that is easy to implement in a small PCB footprint. In the world of analog power-supply design, the inductive DC/DC converter and low-dropout (LDO) regulator are often thought of as key building blocks.

What is a charge-pump converter?

The most fundamental charge-pump converter is the boost, while the charge-pump doubler is the most basic of boost configurations. In this topology, the switching capacitor is charged from the input voltage to ground in the first phase, and then connected between the input voltage and output voltage.
