Power Management IC with Five
Regulated Outputs
Programmed Through 3-Wire
Document order number: MPC18730
Rev 1.0, 10/2005
18730
Serial Interface
The MPC18730 Power Management IC (PMIC) regulates five
independent output voltages from either a single cell Li-Ion (2.7
4.2 V input range) or from a single cell Ni-MH or dry cell (0.9 V to
V input range).
2.2
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 through the serial
interface.

Notes
12. Connect a transistor with gate capacity of 200 pF or smaller to DW_2T and DW_2B
13. If a capacitor with capacitance of 22µF is connected to SREGO, use a phase compensation capacitor between SREGO and SREGC
when the load is 5 mA (6 mA for SREG2) or lower. The output voltage values shown in the table assume that external resistance is
connected as follows:
SREGI1 = 3.0V to 3.3V, 65.14KΩ between SREGO1 and SREGC1, 34.86KΩ between SREGC1 and GND.
SREGI2 = 3.0V to 3.3V, 54.46KΩ between SREGO2 and SREGC2, 45.54KΩ between SREGC2 and GND.
SREGI3 = 3.0V to 3.3V, 73.84KΩ between SREGO3 and SREGC3, 26.16KΩ between SREGC3 and GND.
14. Calculated by the right formula for input offset: SR1OFST=(Vref x 0.77) - (SREGO1 ÷ (100k ÷ 34.86k))
15. Calculated by the right formula for input offset: SR2OFST=(Vref x 1) - (SREGO1 ÷ (100k ÷ 45.54k))
16. Calculated by the right formula for input offset: SR3OFST=(Vref x 0.58) - (SREGO1 ÷ (100k ÷ 26.16k))
17. Connect a transistor with gate capacity of 300 pF or smaller to REG2G.
18. When VGSEL1 is Low and VGSEL2 is Low, I/O=3mA or higher is certified by specification.
19. When VGSEL1 is High and VGSEL2 is Low, I/O=3mA or higher is certified by specification.
20. When HVB is 4.2V and the load from V_STBY is 0.5µA or higher.
