TEA1892DB1226 synchronous rectifier controller add-on board
4.2 Connecting the TEA1892DB1226 add-on board
The TEA1892DB1226 add-on board replaces the existing rectifier diode at the secondary
side of the flyback supply in high-side and low-side applications.
In Figure 7
, the internal and external supply options for high-side applications are shown.
Figure 8
shows the possibilities for low-side applications.

Figure 7(a) shows the connections to be made when the internal charge pump supply is
used. This charge pump generates a V
CC
supply with a value of V
OUT
2 V. The
TEA1892TS supply must be between 8.5 V and 38 V (see Ref. 1
). The V
OUT
voltage must
be between 10.5 V to 40 V. A flyback adapter output voltage is normally within this range.
a. Internal charge pump supply
(1) PSMN3R3-100PS (see Table 5).
b. External auxiliary supply

When there is an auxiliary voltage available in the flyback adapter application, it can be
used to supply the TEA1892TS V
CC
. See Figure 7(b).
In both situations, the MOSFET SOURCE and DRAIN leads are inserted and soldered at
the removed diode D1 anode and cathode connections.
a. Internal charge pump supply
(1) PSMN3R3-100PS (see Table 5).
b. V

supply.
