TEA2206T Description
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 improve up to about 0.7 % at 90 V (AC) mains voltage.
TEA2206T Key Features
- Forward conduction losses of the diode rectifier bridge are reduced
- Very low IC power consumption (2 mW)
- Directly drives two rectifier MOSFETs
- Very low external part count
- Integrated X-capacitor discharge (2 mA)
- Self-supplying
- SO8 package
- Undervoltage lockout
- Drain-source overvoltage protection for all external power MOSFETs
- Gate pull-down currents at startup for all external power MOSFETs
