Overview

TIDA-00459 provides a turnkey solution for the design and evaluation of sensor transmitters and other applications requiring  isolated data transmission and isolated power conversion. The design is based on the LaunchPadTM form factor and showcases a unique power saving methode for transmitting the data accross the isolation barrier. The highly efficient on-board isolated DC/DC converter enables its use in low power applications and applications with limited input power budget like 4- to 20-mA loop powered systems.

Features
  • Low power Isolated single wire bi-directional data transmission up to 1Mbps
  • Highly efficient, optocoupler-less isolated DC/DC converter with 3.3V-output
  • Fully characterized over 3- to 3.6-V input and for load currents up to 10 mA
  • Easily configurable board with LaunchPad™ form factor, expandable by BoosterPack plug-in boards
  • Flexible use by multiple power options, and programmable MCUs on non-isolated and isolated side
