MAX1586A/MAX1586B/MAX1586C/MAX1587A/MAX1587C
General Description
The MAX1586/MAX1587 power-management ICs are optimized for devices using Intel XScaleĀ® 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. The DRAM supply on the A and C devices is preset for 1.8V or 2.5V, while the MAX1586B DRAM supply is preset for 3.3V or 2.5V. The DRAM supply on all parts can also be adjusted with external resistors. The CPU co...
