Reference designs

High-efficiency, low-emission, isolated DC/DC converter-based analog input module reference design

This reference design is a simplified architecture for generating an isolated power supply for isolated amplifiers for measuring isolated voltages and currents. A fully integrated DC/DC converter with reinforced isolation operating from a 5-V input with configurable 5-V or 5.4-V output (headroom for (...)
