LINEAR TECHNOLOGY LT1026 Voltage Converter User's Guide

Summary

The LT1026 is a high-performance switched capacitor voltage doubler and inverter engineered to generate both positive and negative dual supplies ($\pm7\text{V}$ to $\pm18\text{V}$) from a single input source ($4\text{V}$ to $10\text{V}$). This innovative chip eliminates the need for bulky inductors, simplifying power interface designs for various electronics. This technical manual provides engineers and electrical designers with comprehensive details, including detailed electrical characteristics, typical performance graphs, maximum ratings, and application guidelines necessary for implementing reliable logic supplies, op-amps, or data acquisition circuits requiring isolated +/- voltages.
