1 Introduction

Section 2 analyzes the original design from Generating Negative and Positive Voltage Rail With Boost Converter TLV61048 and then using the formula to describe main side effect. To reduce the side effect, the section also provides a design. Section 3 uses Boost Converter± Quick Calculator to design a circuit in specific condition. Section 4 demonstrates the schematic example and layout example for the application.
