High-Efficiency, Low-I PMICs with

Dynamic Core for PDAs and Smart Phones

B6/MAX1587C

General Description

Features

The MAX1586/MAX1587 power-management ICs are

optimized for devices using Intel XScale^®microproces-

sors, including Smart Phones, PDAs, internet appli-

ances, and other portable devices requiring substantial

computing and multimedia capability at low power.

♦ Six Regulators in One Package

Step-Down DC-DC for I/O at 1.3A

Step-Down DC-DC for Memory at 0.9A

Step-Down Serial-Programmed DC-DC for CORE

Up to 0.9A

The ICs integrate seven high-performance, low-operating-

current power supplies along with supervisory and

management functions. Included are three step-down

DC-DC outputs, three linear regulators, and a seventh

always-on output. DC-DC converters power I/O, DRAM,

and the CPU core. The I/O supply can be preset to

3.3V or adjusted to other values. The DRAM supply on

the A and C devices is preset for 1.8V or 2.5V, while the

MAX1586B DRAM supply is preset for 3.3V or 2.5V. The

DRAM supply on all parts can also be adjusted with

external resistors. The CPU core supply is serial pro-

grammed for dynamic voltage management and, on C

devices, can supply up to 0.9A. Linear-regulated out-

puts are provided for SRAM, PLL, and USIM supplies.

Three LDO Outputs for SRAM, PLL, and USIM

Always-On Output for VCC_BATT

♦ Low Operating Current

60µA in Sleep Mode (Sleep LDOs On)

130µA with DC-DCs On (Core Off)

200µA All Regulators On, No Load

5µA Shutdown Current

♦ Optimized for XScale Processors

♦ Backup-Battery Input

♦ 1MHz PWM Switching Allows Small External

Components

♦ Tiny 6mm x 6mm, 40-Pin and 7mm x 7mm, 48-Pin

To minimize quiescent current, critical power supplies

have bypass “sleep” LDOs that can be activated when

output current is very low. Other functions include sep-

arate on/off control for all DC-DC converters, low-bat-

tery and dead-battery detection, a reset and power-OK

output, a backup-battery input, and a two-wire serial

interface.

MAX1587CETL -40°C to +85°C 40 Thin QFN 6mm x 6mm

All DC-DC outputs use fast, 1MHz PWM switching and

small external components. They operate with fixed-fre-

quency PWM control and automatically switch from

PWM to skip-mode operation at light loads to reduce

operating current and extend battery life. The core out-

put can be forced into PWM mode at all loads to mini-

mize noise. A 2.6V to 5.5V input voltage range allows

1-cell lithium-ion (Li+), 3-cell NiMH, or a regulated 5V

input. The MAX1587 is available in a tiny 6mm x 6mm,

40-pin thin QFN package. The MAX1586 features an

additional linear regulator (V6) for VCC_USIM and low-

battery and dead-battery comparators. The MAX1586 is

available in a 7mm x 7mm, 48-pin thin QFN package.

Pin Configurations and Selector Guide appear at end of
