TIDA-00401

Isolated DC/DC Power Supply for PLC Analog Input and Output Module Reference Design

TIDA-00401

Design files

Overview

TIDA-00401 is an isolated DC/DC turn-key reference design. It was designed for a 10-W isolated power supply with wide input voltage range, no opto-coupler feedback and low number of external components. The Fly-Buck™ topology is superior to a flyback design. The single-side populated PCB board provides a convenient tool for evaluation and on-the-fly optimization of the design with adequate headers, jumpers and test points for applications like PLC analog input/output modules.

Features
  • Isolated DC/DC power supply for 15-V to 36-V input and up to 10-W output power
  • Low quiescent current up to 20 mA
  • Open-loop, optocoupler-less design
  • Synchronization output and fixed switching frequency enable use in noise sensitive applications
  • Flexible configurable board enables easy evaluation and modification
  • Design guide provides detailed description and performance test data

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
