VID3 PGND PHASE PVCC PGOOD
ISL6271A
Integrated XScale
Regulator
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.
Since power dissipation inside a microprocessor is proportional to the square of the core vo...
