TEA2206T - NXP

TEA2206T Active bridge rectifier controller

The TEA2206T is an active bridge rectifier controller for replacing the two low-side diodes in the traditional diode bridge with MOSFETs. Using the TEA2206T with low-ohmic high-voltage external MOSFETs significantly improves the efficiency of the power converter as the typical rectifier-diode forwardconduction losses are reduced by 50 %. Efficiency can impro.
