ISL6271ACRZ规格书详情
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 voltage, Intel XScale
processors implement DVM as a means to more efficiently
utilize battery capacity. To support this power saving
architecture, the ISL6271A integrates an I2C bus for
communication with the host processor. The processor, acting
as the bus master, transmits a “voltage level” and “voltage
slew rate” to the ISL6271A appropriate to the processing
requirements; higher core voltages support higher operating
frequencies and code execution. The bus is fully compliant
with the Phillips® I2C protocol and supports both standard
and fast data transmission modes. Alternatively, the output of
the core regulator can be programmed in 50mV increments
from 0.85V to 1.6V using the input Voltage ID (VID) pins. All
three regulators share a common enable pin and are
protected against overcurrent, over temperature and
undervoltage conditions. When disabled via the enable pin,
the ISL6271A enters a low power state that can be used to
conserve battery life while maintaining the last programmed
VID code and slew rate. An integrated soft-start circuit
transitions the ISL6271A output voltages to their default
values at a rate determined by an external soft-start capacitor.
