High-Efficiency, Low-I Q , PMICs with Dynamic
Voltage Management for Mobile Applications
Detailed Description
The MAX8660/MAX8661 PMICs are optimized for
devices using the applications processors, including
smart cellular phones, PDAs, Internet appliances, and
other portable devices requiring substantial computing
and multimedia capability and low power consumption.
The MAX8660/MAX8661 comply with the specifications
for Marvell ’s PXA300 family (PXA3xx) and Marvell ’s
Armada 100 family (PXA16x) of processors.
As shown in Figure 2, the MAX8660 integrates eight
high-performance, low-operating-current power sup-
plies. REG1–REG4 are step-down DC-DC converters,
and REG5–REG8 are linear regulators. Other functions
include low-battery detection ( LBO ), a reset output
( RSO ), a manual reset input ( MR ), and a 2-wire I 2 C seri-
al interface. The MAX8661 functions the same as the
MAX8660, but does not have the REG1 step-down reg-
The operating input voltage range is from 2.6V to 6.0V,
allowing use with a 1-cell Li+ battery, 3-cell NiMH, or a
5V input. Input protection is provided with undervoltage
and overvoltage lockouts. Overvoltage lockout protects
the device against inputs up to 7.5V.
Maxim vs. Marvell PXA3xx Terminology
The MAX8660/MAX8661 are compatible with Marvell‘s
PXA3xx processor. Figure 1 shows one of many possi-
ble connections between the PXA3xx processor and
the MAX8660/MAX8661. To facilitate system develop-
ment with PXA3xx processors, this document uses both
Maxim and Marvell terminology. Marvell terminology
appears in parentheses and italics. For example, this
document refers to “V8 (VCC_BBATT)” because the
MAX8660 V8 output powers the Marvell VCC_BBATT
power domain. Tables 1 and 2 outline Maxim and
Marvell terminology.
