DATASHEET To request the full datasheet, please visit www.intersil.com/products/isl95906 Integrated Power Management IC for VR12.6™ Platforms ISL95906 Features 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. • Highly integrated power management IC • Efficient 1MHz integrated FET switching regulators • Internal compensation, no external compensation • Computer system platform voltage regulators 5V, 3.3V, 1.8V, 1.5V, 1.05V • Programmable VDDQ and VTT regulators for memory (DDR3/L/U, LPDDR3 and DDR4) 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. • Extensive fault protection - Overcurrent protection - Over-temperature protection - Overvoltage and undervoltage protection - Temperature alert signal • Independent power-good indicator for each regulator • Independent enable signals for each regulator for maximum sequencing flexibility 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. • Low power consumption mode for connected standby • I2C bus allows system fault monitoring, enable control and configurable GPIO programming • Output voltage offset programming through I2C • Configuration pin provides additional system programming options Applications • Ultrabook, notebook and tablet computers ADAPTER 2-CELL NVDC CHARGER VSYS X86 or ARM VCORE VCORE 5VAUX, 3A 5VWALKPORT, 3A 3.3VDx and 3.3VDSW, 3A 3.3VSSD, 3A CONFIG EN/GPIO I2C CS# 1.8V, 2A ISL95906 PMIC 1.5V, 2A 1.2V, 8A 0.6V VTTLDO, 1A 1.05VAUX, 5A PGOOD TEMP ALERT FIGURE 1.
