• Manufacturer Part Number: zl2004
• Description: Adaptive Digital Dc-dc Controller With Current Sharing
• Manufacturer: Intersil Corporation

The POLA mode is activated through pin-strap by
connecting a 110 kΩ resistor on V0 to SGND. The V1
pin is then used to adjust the output voltage as shown
in Table 8.
The POLA mode can also be activated through PMBus
commands. See Application Note AN33 for more
details.

DOSA Voltage Trim Mode
On a DOSA module, the V
equation:
To maintain DOSA compatibility, the same scheme is
used as with a POLA module except the 10 kΩ resistor
is replaced with an 8.66 kΩ resistor as shown in Figure
11.
