Preliminary Technical Data
Figure 65. Margining window (Calculator)
Warning prompt
indicating the
attenuation resistor is
too low
Figure 66. Margining window warning prompt
Any one of four mid code voltages can be selected in the software.
These voltages are 0.6V, 0.8V, 1.0V and 1.25V. These four voltages
are typical feedback voltages on many DC/DC Converters. The
DAC’s can be programmed to output a voltage range of +302mV
and -300mv around these mid code voltages. There are a number of
safety features built in to the DAC’s.

Once the calculations are complete the margining window can
then be put into test mode see Figure 67 . This button is
positioned at the bottom left hand corner of the window and is
only visible when all the relevant fields of the calculator have
been filled with data.

Figure 67. Margining window (Test)
The test widow allows the DAC to margin to the limits set in
the calculator window. This is achieved by turning on the DAC
and pressing the margining button. The software will then take
control and margin up or down as is necessary. When the limit
has been reached the software will continue to monitor the
target voltage against the actual voltage. Any drift due to
temperature or load will be detected and the software will
adjust the DAC accordingly.

The DAC outputs are high impedance if not enabled (ie)
they do not interfere with the feedback node of the DC/DC
converter.
Upper/Lower limit registers are provided- once a value is
programmed in these, the output voltage can never rise
above/fall below these values. The Actual DAC Voltage
box in the window above highlights this to the user.
If the Lower Limit is programmed higher than the Upper
limit, the output of the DAC will go high impedance.
