General Description
This is a 5+2 CH integrated PMIC for DV application. There
are 5 DC/DC converters : one synchronous step-up, one
selectable synchronous step-up/step-down, two
synchronous step-downs, and one WLED driver in either
asynchronous step-up or current source mode, selectable
by VOUT6 initial voltage. In addition, there are 2 LDO
regulators : one RTC LDO and one generic LDO. The
generic LDO can choose internal feedback loop for fixed
output 2.5V or external feedback loop for customized
output voltage. Both low voltage synchronous step-up
converters are with load disconnect function. All power
MOSFETs and compensation networks are integrated.
There is a power good indicator to monitor FB2, FB3, and
FB4 voltage status. CH1 to CH5 enabling can be controlled
flexibly : enabled independently or in preset sequences.
