Active, Deep Sleep and Deeper Sleep Modes

The ISL6217 Multi-Phase Controller is designed to control

the CORE output voltage as per the IMVP-IV™ and and

IMVP-IV+™ specifications for Active, Deep Sleep, and

Deeper Sleep Modes of Operation.

After initial start-up, a logic high signal on DSEN# and a

logic low signal on DRSEN signals the ISL6217 to operate

in Active mode (Refer to Table 2). This mode will recognize

VID code changes and regulate the output voltage to these

command voltages
