General Description
The MAX1586/MAX1587 power-management ICs are optimized for devices using Intel XScale® microprocessors, including Smart Phones, PDAs, internet appliances, and other portable devices requiring substantial computing and multimedia capability at low power.
The ICs integrate seven high-performance, low-operatingcurrent 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, DRAM, and the CPU core. The I/O supply can be preset to 3.3V or adjusted to other values.
