DC-DC Conversion Without Inductors

Focus:

This introduction to charge pump voltage converters describes their principles of operation as voltage inverters, doublers, or dividers. A simple model is presented for calculating charge pump power dissipation, and techniques for minimizing power dissipation are discussed. This article reviews trends in the development of charge pump ICs including regulated outputs and buck-boost operation, and provides an overview of charge pump ICs available from Maxim.

What you’ll learn:

• How to understand operation of charge pumps also known as switched-capacitor voltage converters
• How to calculate the power dissipation of charge pumps
• How to understand performance and packaging options available from charge pumps ICs
