Freescale Semiconductor Advance Information Document Number: MPC18730 Rev. 4.0, 8/2006 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 DCDC 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.
