Description

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.
