MAX1586A/MAX1586B/MAX1586C/MAX1587A/MAX1587C
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.
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.
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.
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.
