Integrated Power Management IC For IMVP8™ Platforms
ISL95852
The ISL95852 is a Power Management Integrated Circuit
(PMIC) for ultrabook, notebook and tablet computers powered
by 2-cell Li-ion batteries. It integrates control, MOSFET drivers,
power MOSFETs, fault protection and fault monitoring
functions for three highly efficient synchronous buck
regulators. Integrated into one package are the regulators for
the core, graphics and system agent voltages. The ISL95852 is
offered in a thermally efficient 4mmx4mm, 64-bump, 0.5mm
pitch WLCSP package.
The PMIC regulators convert the system voltage from a battery
or adapter into the three necessary processor voltages
required by Intel’s IMVP8 specifications. The switching
regulators operate at high frequency and are based on
Intersil’s proprietary R3™ Technology, which provides high
light-load efficiency and fast transient response with minimal
external compensation.
The PMIC provides overcurrent, overvoltage and
over-temperature fault protections. Also provided is a
temperature alert signal indicating the PMIC is operating at
elevated temperature and an ALERT signal indicates if any
other fault or warning has occurred. The PMIC also offers I²C
capability compatible with Intel’s SMBus specification.
