Datasheet

However, note the design tool calculates parameters factor-
ing in worst case tolerances, while the equations in the
datasheet based on typical thresholds.
GUI Register Page
The GUI Register Page, as shown in Figure 12, provides the
user with several features to help better understand the func-
tionality of the LM25056. These features include the ability to
read telemetry, device identification and status registers, as
well monitoring the SMBus Alert interrupt.

Telemetry is updated by clicking the Update Telemetry but-
ton. This action will update the fields under the Averaged
heading and under the Immediate heading along with PEAK
PIN. Select which parameters to update by clicking in the box
next to each parameter. If all parameter boxes under a given
heading are checked, the Update will use the block read PM-
Bus commands (AVG_BLOCK_READ and BLOCK_READ)
to update the fields, ensuring that the readings are time
aligned. If one or more of the boxes under the headings is not
checked, the Update will use the respective individual read
PMBus commands to make the telemetry readings and the
measurements will not be time aligned. PEAK PIN is always
read with discrete PMBus commands and, therefore, are nev-
er time aligned. The CLEAR_PIN_PEAK button is provided to
clear the PEAK PIN reading which is often much higher than
one would expect under steady state conditions. This is re-
lated to the large inrush current during power-on that gets
