High-Efficiency, Low-I PMICs with

Dynamic Core for PDAs and Smart Phones

General Description

Features

The MAX1586/MAX1587 power-management ICs are

optimized for devices using Intel X-Scale™ micro-

processors, including third-generation smart cell

phones, PDAs, internet appliances, and other portable

devices requiring substantial computing and multime-

dia 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

Three LDO Outputs for SRAM, PLL, and USIM

Always-On Output for VCC_BATT

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

current power supplies along with supervisory and man-

agement functions. Regulator outputs include three step-

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

seventh always-on output. DC-DC converter outputs

power I/O, DRAM, and the CPU core. The I/O supply can

be preset to 3.3V or 3.0V, or can be adjusted to other val-

ues.The DRAM supply on the MAX1586A and MAX1587A

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 programmed for dynamic volt-

age management. Linear-regulated outputs are provided

for SRAM, PLL, and USIM supplies.

♦ 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 X-Scale Processors

♦ Backup-Battery Input

♦ Separate ON Controls for Any Desired Power

Sequencing

♦ 1MHz PWM Switching Allows Small External

Components

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

To minimize sleep-state quiescent current, critical

power supplies have bypass “sleep” LDOs that can be

activated to minimize battery drain when output current

is very low. Other functions include separate on/off con-

trol for all DC-DC converters, low-battery and dead-bat-

tery detection, a reset and power-OK output, a backup-

battery input, and a two-wire serial interface.

MAX1587AETL -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 is capable of operating in forced-PWM mode at all

loads to minimize ripple and 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 avail-

able 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.
