... Protection features UnderVoltage Protection (UVP) 3. Applications The TEA1795T is intended for resonant power supplies. In such applications, it can drive two external synchronous rectifier MOSFETs which replace diodes for the rectification of the voltages on the two secondary windings of the transformer. It can be used in applications such as: ...

... NXP Semiconductors 11. Application information A switched mode power supply with the TEA1795T consists of a primary side half bridge, a transformer, a resonant capacitor and an output stage. In the output stage SR MOSFETs are used to obtain low conduction loss rectification. These SR MOSFETs are controlled by the TEA1795T. The timing for the synchronous rectifier switch is derived from the voltage difference between the corresponding drain sense and source sense pins ...
