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 applications requiring substantial computing and multimedia capability at low power.
The MAX1702B integrates three ultra-high-performance power supplies with associated supervisory and management functions. Included is a step-down DC-DC converter to supply 3.3V I/O and peripherals, a step-down DC-DC converter to supply 0.7V to VIN for the microprocessor 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 current 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.
