Use LT3487EDD to make DC/DC boost and inverting circuits, which can convert input voltage from 3V-5V to 15V or from 3V-5V to -8V.
This document is a Quick Start Guide for Demonstration Circuit 912, which features the LT3487EDD. The demonstration circuit showcases small size and low component count in both a Boost Circuit and an Inverting Circuit. The Boost Converter converts a 3V-5V input to a 15V output, while the Inverting Circuit generates a -8V output from the same input range.
