High-Efficiency, Low-I , PMICs with Dynamic

Voltage Management for Mobile Applications

0/MAX861

General Description

Features

The MAX8660/MAX8661 power management ICs

(PMICs) power Intel XScale^®applications processors in

smart cellular phones, PDAs, Internet appliances, and

other portable devices.

o Optimized for Intel XScale Processors

o Protected to 7.5V—Shutdown Above 6.3V

o Four Synchronous Step-Down Converters

REG1, REG2, REG3, REG4

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 I²C serial interface. The MAX8661 functions

the same as the MAX8660, except it lacks the REG1

step-down regulator and the REG7 linear regulator.

o Four LDO Regulators

REG5, REG6, REG7, REG8

o 2MHz Switching Allows Small Components

o Low, 20μA 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.
