NXP Semiconductors TEA2206T

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-forward conduction losses are reduced by 50%. Efficiency can improve up to about 0.7% at 90 V (AC) mains voltage.

The TEA2206T is designed in a silicon-on insulator (SOI) process.
