C
SDA / OVP
SDA - power manager
I2C data.
When power manager
I2C is enabled, this is the data connection.
See Section 6 for details.
OVP - over voltage setting.
When power manager
I2C is disabled (VID4 / I2CDIS to 3.3V) the pin is used to set
the OVP protection for CORE and NB sections. Define the OVP threshold by
connecting the pin to the center tap of a voltage divider from 3V3 to SGND.
See Section 8.1 for details.

SCL / OS
SCL - power manager
I2C clock.
When power manager
I2C is enabled, this is the clock connection.
See Section 6 for details.
OS - CORE section offset.
When power manager
I2C is disabled (VID4 / I2CDIS to 3.3V) this pin is internally set
to 1.24V(2.0V): connecting a ROS resistor to GND (3.3V) allows setting a current that
is mirrored into FB pin in order to program a positive (negative) offset according to the
27, 28
PWM4,
PWM3
PWM output for external drivers.
Connect to external drivers PWM inputs. The device is able to manage HiZ status by
setting the pins floating.
By shorting to GND PWM4 or PWM3 and PWM4, it is possible to program the CORE
section to work at 3 or 2 phase respectively.
See Section 5.4.4 for details about HiZ management.

VID5 /
ADDR
Voltage identification pin -
I2C address pin.
Internally pulled-low by 10
μA, it programs the output voltage in PVI mode. In SVI
mode, the pin is monitored on the EN pin rising-edge to modify the
I2C address. See
Section 5 for details.
30
VID4 /
I2CDIS
Voltage identification pin -
I2C disable pin.
Internally pulled-low by 10
μA, it programs the output voltage in PVI mode. In SVI
mode, the pin is monitored on the EN pin rising-edge to enable/disable the
I2C. See
Section 5 for details.
31
VID3 / SVC
Voltage IDentification Pin - SVI clock pin.
Internally pulled-low by 10
μA, it programs the output voltage in both SVI and PVI
modes. In SVI mode, the 10
μA pull down is disabled. See Section 5 for details.
32
VID2 / SVD
Voltage identification pins - SVI data pin.
Internally pulled-low by 10
μA, it programs the output voltage in both SVI and PVI
modes. In SVI mode, the 10
μA pull down is disabled. See Section 5 for details.

VID1 /
CORETYPE
Voltage identification pin.
Internally pulled-low by 10
μA, it programs the output voltage in PVI mode. The pin is
monitored on the EN pin rising-edge to define the operative mode of the controller
(SVI or PVI). See Section 5 for details.
34
VID0 / VFIX
Voltage identification pin.
Internally pulled-low by 10
μA, it programs the output voltage in PVI mode. If the pin is
pulled to 3.3V, the device enters V_FIX mode and SVI commands are ignored.
See Section 5 for details.
