Integrated Power Management IC for VR12.6™
Platforms
ISL95906
The ISL95906 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 8 highly efficient, synchronous buck regulators
and VTT LDO. It is offered in a thermally efficient
5.5mmx5.5mm, 121 bump, 0.5mm pitch WLCSP package.
The PMIC regulators convert system voltage from the battery
or adapter into all platform voltages needed for a typical
computer system including 5V and 3.3V system regulators,
1.8V, 1.5V, 1.05V for controller-hub, peripheral and core
voltages as well as programmable VDDQ and VTT regulators
for DDR3/3U/3L, LPDDR3 and DDR4 voltages. The switching
regulators operate at 1MHz and are based on Intersil’s
proprietary R4™ Technology, which provides high light-load
efficiency, fast transient response, seamless DCM/CCM
transitions and requires no external compensation.
The PMIC provides overcurrent, overvoltage and
over-temperature fault protections and undervoltage and
over-temperature warnings. A temperature alert signal
indicates the PMIC is operating at an elevated temperature
and ALERT indicates if any other fault or warning has occurred.
The PMIC also offers significant I2C capability and can be
configured to provide 8 GPIO pins for additional system
functionality and each regulator has an independent
power-good indicator.
