MAX8588ETM
High-Efficiency, Low-IQ PMIC with Dynamic Core for PDAs and Smartphones
General Description
The MAX8588 power-management IC is optimized for
devices using Intel X-Scale™ microprocessors, includ-
ing smartphones, PDAs, internet appliances, and other
portable devices requiring substantial computing and
multimedia capability at low power.
The IC integrates 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, memo-
ry, and the CPU core. The I/O supply can be preset to
3.3V or adjusted to other values.The DRAM supply is
preset for 3.3V or 2.5V, or it can be adjusted with exter-
nal resistors. The CPU core supply is serial pro-
grammed for dynamic voltage management and can
supply up to 0.5A. Linear-regulated outputs are provid-
ed 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 MAX8588 is available in a tiny 6mm x 6mm,
48-pin thin QFN package.

Note 1:Dropout voltage is guaranteed by the p-channel switch resistance and assumes a maximum inductor resistance of 45mΩ.
Note 2:The PWM-skip-mode transition has approximately 10mA of hysteresis.
Note 3:The maximum output current is guaranteed by the following equation:
where:
and RN = n-channel synchronous rectifier RDS(ON)
RP = p-channel power switch RDS(ON)
RL = external inductor ESR
IOUT(MAX) = maximum required load current
f = operating frequency minimum
L = external inductor value
ILIMcan be substituted for IOUT(MAX) (desired) when solving for D. This assumes that the inductor ripple current is
small relative to the absolute value.
Note 4:POK only indicates the status of supplies that are enabled (except V7). When a supply is turned off, POK does not trigger
low. When a supply is turned on, POK immediately goes low until that supply reaches regulation. POK is forced low when all
supplies (except V7) are disabled.
Note 5:Specifications to -40°C are guaranteed by design, not production tested.
