7. PMBus Commands Description

INTERLEAVE (37h)

Definition: Configures the phase offset of a device that is sharing a common SYNC clock with other devices. The

phase offset of each device can be set to any value between 0° and 360° in 22.5° increments. The internal two phases of

the module always maintain a phase difference of 180°.

Data Length in Bytes: 2

Data Format: BIT

Type: R/W

Default Value: 0021h (Page0), 0022h (Page1)

Units: N/A

IOUT_CAL_GAIN (38h)

Definition: Sets the effective impedance across the current sense circuit for use in calculating output current at +25°C.

Data Length in Bytes: 2

Data Format: L11

Type: R/W

Default Value: Ch1: B2C3(0.69mΩ); Ch2: B2D7(0.7mΩ)

Units: mΩ

IOUT_CAL_OFFSET (39h)

Definition: Nulls out any offsets in the output current sensing circuit for each phase, and compensates for delayed

measurements of current ramp due to ISENSE blanking time.

Data Length in Bytes: 2

Data Format: L11

Type: R/W

Default Value: Ch1: B529(-0.71A); Ch2: BDDC(-1.07A)

Units: A

VOUT_OV_FAULT_LIMIT (40h)

Definition: Sets the VOUT overvoltage fault threshold.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: 1.15xVOUT_COMMAND pin-strap setting

Units: V

Range: 0V to VOUT_MAX
