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, ...
