Integrated XScale Regulator Evaluation Board


The ISL6271AEVAL1 evaluation board provides a means to explore and validate the functional capabilities of the ISL6271A XScale regulator. The ISL6271A is a power management integrated circuit (PMIC) designed to provide the low-voltage requirements for the Bulverde XScale processor.

The ISL6271A is a versatile power management IC (PMIC) designed for the Xscale type of processors. The device integrates three regulators, two fault indicators and an I2C bus for communication with a host microprocessor. Two of the three regulators function as low power, low drop out regulators, designed to power SRAM and phase-lock loop circuitry internal to the Xscale processor. The third regulator uses a proprietary switch-mode topology to power the processor core and facilitate Dynamic Voltage Management (DVM), as defined by Intel.
