Server power supplies are used in parallel redundancy to ensure system reliability. Schottky diodes offer the lowest voltage drop, but power losses can be excessive as output current increases. In the same manner that MOSFETs can reduce losses in secondary rectification, MOSFETs can also be employed to reduce losses in the ORing function. International Rectifier offers a wide range of low voltage, high current, low on-resistance MOSFETs to fulfill ORing needs.
