MAX1586ETM
0.3-6.0V; high-efficiency, low-Iq PMICs with dynamic core for PDAs and smart phones. For PDA, palmtop and wireless handhelds, 3-generation smart cell phones, internet appliances and web-books
General DescriptionThe 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.
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 andMAX1587A
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.
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.
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
