Description

LDOC_ENA_SA

read-write

If set, LDO C is enabled in StandAlone mode, independent

of the DCDC A Buck/Boost converter.

In EM4, this bit is treated as zero, which means LDO C will

be disabled.

Standalone Mode should not be enabled if the DCDC A is

configured for wiredBuckLDO (BB_MODE==5) and the

VOA and VOC outputs are shorted together in hardware. If

LDOC_ENA_SA is set in that configuration, both LDOC C

and DCDC A will attempt to drive the same output, with

the higher voltage winning. This may trip the overvoltage

protection, resulting in unintended current draw.

LDOC_BYP

read-write

If set, LDO C acts only as a bypass switch (i.e., the input is

shorted to the output).

5:4

LDOC_VMIN

0x00

read-write

Defines voltage at which output current becomes voltage

independent for LDO C. Recommended to set

LDOC_VMIN based on the target VOC voltage as given

below:

LDOC_VMIN=3 for VOC targets >=2.7V

LDOC_VMIN=2 for VOC targets between 2.4V and 2.7V

LDOC_VMIN=1 for VOC targets between 2.0V and 2.4V

LDOC_VMIN=0 for VOC targets < 2.0V

3:0

LDOC_IGAIN

0x00

read-write

Determines the maximum output current supported by

LDO C. Recommend to set to the maximum expected load

current plus some margin.

i_max = VOC / (2.76 * ( 17 - LDOC_IGAIN ) )
