Abstract
This user manual describes how the TEA1892DB1226 add-on board can
be used in a flyback converter. The add-on board contains a TEA1892TS
SR controller in TSOP-6 package. The add-on board also contains a
power MOSFET, as well as a charge pump circuit to generate the supply
voltage for the SR controller. The add-on board replaces the rectifier diode
at the secondary side of the flyback converter. It is intended for high-side
applications, but with minor modifications it can also be used for low-side
applications.
