The TEA1762T is the controller for synchronous rectification to be used in discontinuous
conduction mode and quasi resonant flyback converters. Besides controlling the
SR MOSFET, the TEA1762T contains the voltage reference and amplifiers to regulate and
control the output voltage and output current of the power supply.
