Performance parameters of ZY7120 POL converters
can be programmed via the industry standard I
communication
components
parameter has a default value stored in the volatile
memory registers detailed in Table 1.
registers 00h through 14h are programmed at the
system power-up.
performance parameters, the values in the registers
are overwritten. Upon removal of the input voltage,
the default values are restored.

ZY7120 converters can be programmed using the
Graphical User Interface or directly via the I
using high and low level commands as described in
the ‘”DPM Programming Manual”.
ZY7120 parameters can be reprogrammed at any
time during the system operation and service except
for the digital filter coefficients, the switching
frequency and the duty cycle limit, that can only be
changed when the POL is turned off.

The output voltage can be programmed in the GUI
Output Configuration window shown in the Figure 27
or directly via the I
register shown in Figure 28.
