The MT6363 SPMI PMIC provides 10 BUCK and 25 LDO (Low DropOut) regulators
|
|
and can optionally provide overcurrent warnings with one ocp interrupt
|
|
for each voltage regulator.

Allowed Buck regulator operating modes allowed. Valid values below.
|
|
0 - Normal mode with automatic power saving, reducing the switching
|
|
frequency when light load conditions are detected
|
|
1 - Forced Continuous Conduction mode (FCCM) for improved voltage
|
|
regulation accuracy with constant switching frequency but lower
|
|
regulator efficiency
|
|
2 - Forced Low Power mode for improved regulator efficiency, used
|
|
when no heavy load is expected, does not limit the maximum out
|
|
current but unless only a light load is applied, there will be
|
|
regulation accuracy and efficiency losses.
|
|
3 - Forced Ultra Low Power mode for ultra low load, this greatly
|
|
reduces the maximum output power, makes the regulator to be
|
|
efficient only for ultra light load, and greatly reduces the
|
|
quiescent current (Iq) of the buck.
