PMICs optimized to support subsystem peripheral power requirements
Update Time: 2019-12-20 23:53:34
Highly integrated power management ICs (PMICs) that enable the industry’s first credit card-size motherboards for high-end ultrabook and tablet computers are powered by 2-cell Li-ion batteries. The single-chip ISL95908 PMIC delivers eight voltage rails optimized to support subsystem peripheral power requirements for new Intel IMVP8 platforms, and the single-chip ISL95906 provides eight power rails for VR12.6-compliant systems. The devices measure 5.5mm x 5.5mm, enabling PC motherboards that are 75% smaller than previously possible using discrete switchers, inductors and capacitors.
The ISL9590x PMICs address the trend toward slimmer ultrabooks, tablets and 2-in-1 computers that offer more features and longer battery life. Both PMICs integrate a controller, power and driver MOSFETS, VTT LDO regulator, independent enable and power-good indicators, I2C interfaces, and fault protection/monitoring for eight synchronous buck regulators. They deliver 90% efficiency and integrate 2x more functionality than the nearest competitor, allowing designers to use fewer external components, including smaller, low-profile inductors and capacitors. Now mobile computing OEMs only need three devices – PMIC, core voltage regulator and battery charger – to power up the CPU/GPU, battery, and subsystem peripherals: flash memory, USB, HDMI, audio, sensors, camera module and WiFi.
The ISL9590x are the industry’s only single-chip solutions that support the Intel and Microsoft Connected Standby standard, which provides an instant-on, always-connected experience similar to smartphones. The Connected Standby low-power mode maintains Internet connectivity, email and applications while the system is asleep. Both PMICs employ Intersil’s proprietary R4 modulation technology, which delivers high light-load efficiency, ultra-fast transient response, and seamless continuous-conduction mode (CCM) and discontinuous-conduction mode (DCM) transitions.
