TEA2208T中文资料Active Bridge Rectifier Controller数据手册恩XP规格书

描述 Description

The TEA2208T is the first product of a new generation of active bridge rectifier controllers replacing the traditional diode bridge.
Using the TEA2208T with low-ohmic high-voltage external MOSFETs significantly improves the efficiency of the power converter as the typical rectifier diode-forward conduction losses are eliminated. Efficiency can improve up to about 1.4 % at 90 V (AC) mains voltage.
The TEA2208T is designed in a silicon-on insulator (SOI) process.
