This document introduces a dual DC/DC converter with integrated Schottky diodes, which generates ±40V outputs and consumes only 40µA quiescent current. The converter is suitable for portable devices with high accuracy and wide input and output voltage ranges.
Design Note 359 introduces the LT3463, a compact dual DC/DC converter designed to generate accurate high voltage bias supplies. The device integrates Schottky diodes and switches into a tiny DFN package, eliminating the need for bulky transformers or capacitor arrays typically used in charge pumps.
The device generates outputs up to +40V.
Each converter operates with a quiescent current of 20uA.
The device works with an input voltage range from 2.3V to 15V.
