will re-initialize, the Module Operational Command (01h) and Module Write Protect Command (10h) will be
set to enable. The module output will be ON and set to nominal V out.
Table 4-17 lists the status of the module command and the functionality of the commands when configuring
the module to DVS mode.

in DVS
Upon Change to DVS
B1h
VREF
Yes
Set to the module’s nominal output voltage.
B2h
IREF
Yes
IREF is the output current level in which the
module will enter to Constant Current Source.
During 52h set to Constant Current, value will be
set based on Module Command 4Dh and nominal
output current.
During 52h set to Latch Type, although the Latch
level can be adjusted, the IREF value will be fixed
to 120% of the nominal output current.

*Before writing to the module, please ensure that the Module Command Write Protect (10h) is disabled.
*Please refer to Section 5.2 for Module User Configurable Parameters or Appendix B.2 Module Command
The user can program the module’s output voltage within 5% to 120% of the nominal output voltage rating of
the module. For example, a 24V module has a nominal voltage of 24V and can be set to operate between 1.2V
and 28.8V.
