OUTPUT DISCHARGE FUNCTION CONFIGURATION),

ADDRESS 0x06

discharge switch setting for Channel 1 to Channel 4. The

PSMx_ON bit setting for each channel is in effect when the

SYNC/MODE pin is high (or when SYNC/MODE is configured

as a clock input or output). When the SYNC/MODE pin is low,

all channels are forced to work in automatic PWM/PSM mode,

and the PSMx_ON settings in this register are ignored. The default

value for the output discharge function can be programmed by

factory fuse (output discharge function enabled or disabled for

all four buck regulators).

Description

DSCG4_ON

R/W

The default value is programmed by factory fuse.

0 = disable output discharge function for Channel 4.

1 = enable output discharge function for Channel 4.

DSCG3_ON

R/W

The default value is programmed by factory fuse.

0 = disable output discharge function for Channel 3.

1 = enable output discharge function for Channel 3.

DSCG2_ON

R/W

The default value is programmed by factory fuse.

0 = disable output discharge function for Channel 2.

1 = enable output discharge function for Channel 2.

DSCG1_ON

R/W

The default value is programmed by factory fuse.

0 = disable output discharge function for Channel 1.

1 = enable output discharge function for Channel 1.

PSM4_ON

R/W

This bit is ignored when the SYNC/MODE pin is low.

0 = enable forced PWM mode for Channel 4 (default).

1 = enable automatic PWM/PSM mode for Channel 4.

PSM3_ON

R/W

This bit is ignored when the SYNC/MODE pin is low.

0 = enable forced PWM mode for Channel 3 (default).

1 = enable automatic PWM/PSM mode for Channel 3.

PSM2_ON

R/W

This bit is ignored when the SYNC/MODE pin is low.

0 = enable forced PWM mode for Channel 2 (default).

1 = enable automatic PWM/PSM mode for Channel 2.

PSM1_ON

R/W

This bit is ignored when the SYNC/MODE pin is low.

0 = enable forced PWM mode for Channel 1 (default).

1 = enable automatic PWM/PSM mode for Channel 1.
