Triple-Output Power-Management IC for
Microprocessor-Based Systems
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
