The ISL95862 from Intersil 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 ISL95862 is offered in a thermally efficient 8mmx12mm, 96 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. The controller also features a temperature alert signal that indicates when the PMIC is operating at an elevated temperature.
An ALERT signal provides notice of any fault or warning outside of the temperature alert signal. The PMIC also offers I2C capability compatible with Intel's SMBus specification.
