Overview

The SWIFTINV-CALC Excel sheet is a complementary worksheet to the SLVA317 application note. The worksheet is used to calculate the external components needed to create a negative output voltage from a positive input voltage. The tool features several families of wide input voltage, current-mode controlled SWIFT DC/DC converters in an inverting buck boost topology.
