CLEAR_FAULTS (03h)

Definition: Clears all fault bits in all registers and releases the SALRT pin (if asserted) simultaneously. If a fault condition still exists, the

bit will reassert immediately. This command will not restart a device if it has shut down, it will only clear the faults.

Data Length in Bytes: 0 Byte

Data Format: N/A

Type: Write only

Default Value: N/A

Units: N/A

Reference: N/A

STORE_USER_ALL (15h)

Definition: Stores all PMBus settings from the operating memory to the nonvolatile USER store memory. To clear the USER store,

perform a RESTORE_FACTORY then STORE_USER_ALL. To add to the USER store, perform a RESTORE_USER_ALL, write commands to

be added, then STORE_USER_ALL. This command can be used during device operation, but the device will be unresponsive for 20ms

while storing values.

Data Length in Bytes: 0

Data Format: N/A

Type: Write only

Default Value: N/A

Units: N/A

RESTORE_USER_ALL (16h)

Definition: Restores all PMBus settings from the USER store memory to the operating memory. Command performed at power-up.

Security level is changed to Level 1 following this command. This command can be used during device operation, but the device will be

unresponsive for 20ms while storing values.

Data Length in Bytes: 0

Data Format: N/A

Type: Write only

Default Value: N/A

Units: N/A

VOUT_MODE (20h)

Definition: Reports the VOUT mode and provides the exponent used in calculating several VOUT settings. Fixed with linear mode with

default exponent (N) = -13

Data Length in Bytes: 1

Data Format: BIT

Type: Read-only

Default Value: 13h (Linear Mode, N = -13)

Units: N/A

VOUT_COMMAND (21h)

Definition: Sets or reports the target output voltage. This command cannot set a value higher than either VOUT_MAX or 110% of the pin

strap VOUT setting.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: Pin strap setting

Units: Volts

Range: 0V to VOUT_MAX
