General Notes: 1. This subset of Champs’ 168F1 series is earmarked to function in No-Opto Isolated Flyback circuits as described by the LT8302 and LT8304 ICs from Analog Devices. 2. Input Voltage and Output Power Ratings are a function of the IC’s on-board FET and not a limitation of the transformer. In other applications the 168F1 part can operate over a wider Vin range or greater output power. Increased height allows increased power output due to higher current capability. 3. Integer Turns available from 1T to 16T. Can be used as Primary or Secondary. Mechanical configuration and outline allow for a “flex” arrangement. Contact factory for information on any flyback topology design. 4. All designs can be supplied with planar windings as embedded in the pcb of the Main Module of the converter. Heat Sink and installed power components SM assembly and installation are also available. 5.  All transformers installed with associated power components are available from Champs as Main Modules to be installed as a functioning DC-DC converter application. Accompanying Base-Boards ease the task of evaluation. Aspects of this construction are patent pending concepts of Champs and are made available as “open source”.
