High-Efficiency, Low-I Q , PMICs with Dynamic
Voltage Management for Mobile Applications
General Description
The MAX8660/MAX8661 power management ICs
(PMICs) power applications processors (APs) in smart
cellular phones, PDAs, Internet appliances, and other
portable devices.
Four step-down DC-DC outputs, three linear regulators,
and an 8th always-on LDO are integrated with power-
management functions. Two dynamically controlled DC-
DC outputs power the processor core and internal mem-
ory. Two other DC-DC converters power I/O, memory,
and other peripherals. Additional functions include on/off
control for outputs, low-battery detection, reset output,
and a 2-wire I 2 C serial interface. The MAX8661 functions
the same as the MAX8660, except it lacks the REG1
step-down regulator and the REG7 linear regulator.
Features
o Optimized for Marvell’s PXA300 and Armada 100
Family of Processors
o Protected to 7.5V—Shutdown Above 6.3V
o Four Synchronous Step-Down Converters
REG1, REG2, REG3, REG4
o Four LDO Regulators
REG5, REG6, REG7, REG8
o 2MHz Switching Allows Small Components
o Low, 20 μ A Deep-Sleep Current
o Low-Battery Monitor and Reset Output
Ordering Information
All step-down DC-to-DC outputs use fast 2MHz PWM
switching and tiny external components. They automati-
cally switch from PWM to high-efficiency, light-load
operation to reduce operating current and extend bat-
tery life. In addition, a forced-PWM option allows low-
noise operation at all loads. Overvoltage lockout pro-
tects the device against inputs up to 7.5V.
Applications
PDAs, Palmtops, and Wireless Handhelds
