Data Sheet

Register 29 selects the power-up/power-down control mode for Channel 1 to Channel 7: I2C control (manual) mode or sequencer mode

(for more information, see the Enabling and Disabling the Output Channels section). The default values are defined by the fuse option.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN6

R/W

This bit sets the power-up/power-down control mode for Channel 6.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN5

R/W

This bit sets the power-up/power-down control mode for Channel 5.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN4

R/W

This bit sets the power-up/power-down control mode for Channel 4.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN3

R/W

This bit sets the power-up/power-down control mode for Channel 3.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN2

R/W

This bit sets the power-up/power-down control mode for Channel 2.

0 = I2C control mode.

1 = sequencer mode.

MODE_EN1

R/W

This bit sets the power-up/power-down control mode for Channel 1.

0 = I2C control mode.

1 = sequencer mode.

Register 30 sets the regulation mode for Channel 6 (buck boost or buck only) and adjusts the threshold of the boost regulator kick-in

point when Channel 6 is configured for buck boost regulation mode (for more information, see the Channel 6: Buck or Buck Boost

Regulator section). The default values are defined by the fuse option.
