TEA2206T Overview
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 %.
Key Features
- Forward conduction losses of the diode rectifier bridge are reduced
- Very low IC power consumption (2 mW) 2.2 Application features
- Directly drives two rectifier MOSFETs
- Very low external part count
- Integrated X-capacitor discharge (2 mA)
- Self-supplying
- SO8 package 2.3 Control features
- Undervoltage lockout
- Drain-source overvoltage protection for all external power MOSFETs
- Gate pull-down currents at startup for all external power MOSFETs
