General Description
The MAX1702B power-management IC supports ARM
Powered
devices such as the Intel
PXA210 and
PXA250 microprocessors based on the Intel XScale
micro-architecture. These devices include PDAs, third-
generation smart cellular phones, internet appliances,
automotive in-dash Telematics systems, and other appli-
cations requiring substantial computing and multimedia
capability at low power.
The MAX1702B integrates three ultra-high-performance
power supplies with associated supervisory and man-
agement functions. Included is a step-down DC-DC con-
verter to supply 3.3V I/O and peripherals, a step-down
DC-DC converter to supply 0.7V to V
IN
for the micro-
processor core, and a step-down DC-DC converter to
supply either 1.8V, 2.5V, or 3.3V to power the memory.
Management functions include automatic power-up
sequencing, power-on-reset and manual reset with timer,
and two levels of low-battery detection.
The DC-DC converters use fast 1MHz PWM switching,
allowing the use of small external components. They
automatically switch from PWM mode under heavy loads
to skip mode under light loads to reduce quiescent cur-
rent and maximize battery life. The input voltage range is
from 2.6V to 5.5V, allowing the use of three NiMH cells, a
single Li+ cell, or a regulated 5V input. The MAX1702B is
available in a tiny 6mm x 6mm, 36-pin QFN package and
operates over the -40°C to +85°C temperature range.
