Description

The TIDA-00706 reference design is a 25W: multiple output: auxiliary power supply designed for use in power converters targeted for Server: Telecom and Industrial system applications. This solution is a multiple output flyback converter implemented using the  UCC28700 to provide Constant-Voltage (CV) and Constant-Current (CC) output regulation and uses quasi-resonant valley-switching to achieve higher efficiency. The design is compact and low cost due to minimal component count with all the necessary built-in protections such as output overcurrent and output short circuit.  Hardware is designed and tested to pass EFT requirements and meets low power efficiency performance of Department of Energy (DoE) Level VI standards.  Additionally: the design has a built-in eFuse for  fault isolation on 12V main rail without affecting any other outputs.
