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.
