Reference Voltage
The TPS65552A does not have its own reference voltage circuit inside, and the TPS65552A uses the VCC input
voltage as a reference to detect I
(PEAK)
, V
(ZERO)
, and V
(FULL)
. Therefore, voltage input at VCC is approximately
5 V.
Termination Voltage Setting
To obtain a different termination voltage, transformers of different turn ratio are required.
Table 2
shows the
matrix of termination voltage and the turn ratio of the transformer. The table only shows a
ONE to integer
ratio
while there are no limitations for a turn ratio of the transformer in a real application circuit, example 1:10.5 (=
10:105).

SLVS567–JULY 2005
VCC differs from 5 V by system limitations.
Table 1
shows the dependence of each function of TPS65552A to
VCC.
