Efficient, low-loss synchronous rectification
The European distributor ECOMAL has introduced the first Schottky barrier rectifiers from Vishay Technology which use trench MOS technology. These devices appear in the equivalent circuit diagram as an MOS element and Schottky metal in parallel. New environmental guidelines including EUP (Energy – Using – Products 2005/32/EC), which are intended to save as much energy as possible and minimize the tolerable losses in the overall system, require highly efficient circuit designs.
The if favor of the new technology.
Synchronous rectification on the secondary side using MOSFETs can significantly reduce power losses in telecommunications systems, industrial power supplies and distributed power systems. However, these devices are expensive and require appropriate control electronics. This complicates the design and drives up production costs.
