10 APPLICATION INFORMATION
A typical application diagram of the TZA1032 is shown in
Fig.4. As can be seen from this figure the CLKP, CLKN,
DATAP and DATAN inputs allow differential data transfer
for electromagnetic compatibility issues. Input series
resistors can be connected to obtain low voltage swing
when using standard 3.3 or 5 V drivers. This will further
reduce electromagnetic interference.
This application diagram shows separated 3.3 V supplies
to obtain maximum output performance. Only few
decoupling capacitors are needed for the total application.

The forward sense loop is fully self-contained. Only a
forward sense diode has to be connected, which can be
biased with an external voltage.
The TZA1032 can be mounted with ‘flip-chip’ technology
as a bare die on the flex foils. For this purpose the bond
pads of the silicon die can be bumped with solder dots.
In this configuration parasitic components (e.g. inductors)
can be further reduced leading to even better performance
of the TZA1032.
