Power Management IC with Five
Regulated Outputs
Programmed Through 3-Wire
Serial Interface
The MPC18730 Power Management IC (PMIC) regulates five
independent output voltages from either a single cell Li-Ion (2.7 V to
4.2 V input range) or from a single cell Ni-MH or dry cell (0.9 V to
2.2 V input range).
The PMIC includes 2 DC-DC converters and 3 low drop out (LDO)
linear regulators. The output voltage for each of the 5 output voltages
is set independently through a 3-wire serial interface. The serial
interface also configures the PMIC's versatile start-up control system,
which includes multiple wakeup, sleep, standby, and reset modes to
minimize power consumption for portable equipment.
In single cell Li-Ion applications two DC-DC converters are
configured as buck (step-down) regulators. In single cell Ni-MH or dry
cell applications, one DC-DC converter is configured as a boost
(step-up) regulator, and the other as buck-boost regulator. The DC-
DC converters' output voltages have set ranges 1.613 V to 3.2 V at
up to 120 mA, and 0.805 V to 1.5 V up to 100 mA through the serial
interface.
