ISL95852
All-in-One PMIC for IMVP8 Vcore
The ISL95852 is a Power Management Integrated Circuit
(PMIC) for 2-in-1, ultrabook and tablet computers powered
by 1- and 2-cell Li-ion batteries. It integrates control, MOSFET
drivers, power MOSFETs, fault protection, and fault monitoring
functions for three highly effi cient synchronous buck regulators
for the core, graphics and system agent voltages.
• Highly integrated power management IC
•
Effi cient high frequency integrated FET switching regulators
• Integrated regulators to produce core, graphics and system
agent rails
•
Extensive fault protection
–
Overcurrent, overvoltage and over-temperature protection
–
