Notes
30. All combinations of input are not included
ON to output the VO2_SENSE_IN voltage to VOUT2. If you
turn DDC2 OFF using the register, the power switch 2 also
turns OFF. Capacitance value which is connected to
VO2_SENSE_IN should be higher than the capacitor
connected to VOUT2.
POWER SUPPLY VO1_SENSE, VO2_SENSE:
LI-ION
The VBATT voltage falls and is output to VO1_SENSE.
When using Li_ion, duty limit due to DMAX1 is not applied to
the switch. When PGOOD2(int) is High, the power switch
turns ON to output the VO1_SENSE voltage to VOUT1.
Capacitance value which is connected to VO1_SENSE
should be higher than the capacitor connected to VOUT1.
SERIES PASS POWER SUPPLY
The series pass outputs the SREGI1 voltage to SREGO1,
the SREGI2 voltage to SREGO2, and the SREGI3 voltage to
SREGO3. If you use MOSFET as the external component in
this case, connect the gate to SREG2G.
The VBATT voltage falls using only the internal transistor
and is output to VO2_SENSE. When using Li_ion, duty limit
due to DMAX2 is not applied to the switch, and HG and LG
are Low. When PGOOD2(int) is High, the power switch turns
