This example configures 1.2 V in
VBUCKA_CTRL_A
and 0.8 V in
VBUCKA_CTRL_B
. After
asserting the
BUCK_SEL
bit the DVC transition in the output voltage is as shown in
Figure 16: DVC Transition
The voltage is decreased by 400 mV in approximately 40 µs, therefore, the slope of the DVC
transition can be seen as 10 mV/µs.
The value can be set on the
SLEW_RATE1
field of
CONTROL_A
register. This field is located on
the
Buck
tab of the GUI, as shown by the red arrow in
Do not confuse the slew rate setting of DVC voltage changes with the UP_CTRL, DOWN_CTRL of
each buck, as they do only refer to the power up and power down slope.
