Champs-Tech UY38+ Series PSFB: FWCT + Current Doubler Transformers

General Notes:

1.  Topology: PSFB to Current Doubler and FWCT DC-DC Converter applications.

2. Add thermal pads in combination with heat sinks and clamps allows for higher power throughput at rated ambient and hot spot temperatures.

3. Size: 25mm wide x 48mm length x 10-12mm Height

4. Multilayer PCB optimization for lowest AC resistance & Proximity Loss Effect

5. Integer Turns available from 1T to 40T.                               .

6. All designs can be supplied with planar windings embedded in the pcb of the Main Module of the converter. Installed power components, SM Assy and Heat Sink + incorporation into a module available.                     

7. Wide variety of PNs, Designs and Turns Ratios in stock. If not listed, Contact Us

8. Surface Mount, Thru-Hole, Pad-to-Pad, Embedded Planar Windings as Options
