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 Intel® Bulverde XScale processor.

The ISL6271A is a versatile 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.
