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

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).
