ADP5055-EVALZ
Enabling the Dynamic Voltage Scaling (DVS)
The ADP5055 provides a DVS function for Channel 1 to
Channel 3. These reference voltages can be programmed in real
time via the PMBus serial interface in Register 0xDC (DVS_LIM1)
to Register 0xDE (DVS_LIM3). The DVS_INTVALx bits in
Register 0xDB (DVS_CFG) are used to set the step interval during
the transition for individual channels.
Figure 17 shows a typical DVS voltage transition.
