6.2 Pin description
7. Functional description
The TEA1762T is the controller for synchronous rectication to be used in discontinuous
conduction mode and quasi resonant yback converters. Besides controlling the
SR MOSFET, the TEA1762T contains the voltage reference and ampliers to regulate and
control the output voltage and output current of the power supply.
