Single Resistor Output Voltage Setting Mode
Some applications desire the output voltage to be set using a
single resistor. This can be accomplished using a resistor on the

SMBus Mode
V IN
The output voltage may be set to any value between 0.6V and
5.0V using a PMBus command over the I 2 C/SMBus interface.
See Application Note AN2033 for details.

If the device is to be synchronized to an external clock source, the
clock frequency must be stable prior to asserting the EN pin. The
device requires approximately 5ms to 10ms to check for specific
values stored in its internal memory. If the user has stored values
in memory, those values will be loaded. The device will then
check the status of all multi-mode pins and load the values
associated with the pin settings.
Once this process is completed, the device is ready to accept
commands via the I 2 C/SMBus interface and the device is ready
to be enabled. Once enabled, the device requires a minimum
delay period following an enable signal and prior to ramping its
been configured (using PMBus commands), the device will
default to the minimum delay period. If a delay period greater
than the minimum is configured, the device will wait for the
configured delay period prior to starting to ramp its output.
After the delay period has expired, the output will begin to ramp
towards its target voltage according to the pre-configured
soft-start ramp time that has been set using the SS pin. It should
be noted that if the EN pin is tied to VDD, the device will still
require approximately 5ms to 10ms before the output can begin
its ramp-up as described in Table 5.
