19-3527; Rev 0; 3/05 www.DataSheet4U.com High-Efficiency, Low-IQ PMIC with Dynamic Core for PDAs and Smartphones General Description The MAX8588 power-management IC is optimized for devices using Intel X-Scale™ microprocessors, including smartphones, PDAs, internet appliances, and other portable devices requiring substantial computing and multimedia capability at low power. The IC integrates 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, memory, and the CPU core. The I/O supply can be preset to 3.3V or adjusted to other values. The DRAM supply is preset for 3.3V or 2.
