Intersil’s announces highly integrated PMICs for Tablets and Ultrabooks

Intersil

Intersil Corporation presented a pair of exceedingly highly integrated power management ICs (PMICs) that empower the business’ first credit card size motherboards for top of the line ultrabook and tablet PCs powered by 2-cell Li-ion batteries. The single-chip ISL95908 PMIC conveys eight voltage rails improved to support subsystem peripheral power requirements for new Intel IMVP8 platform, and the single-chip ISL95906 gives eight power rails to VR12.6-compliant systems. . The device measure 5.5mm x 5.5mm, empowering PC motherboards that are 75% smaller than beforehand conceivable utilizing 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.

“Our customers are innovating in smaller and thinner form factors and Intersil’s latest PMIC solutions offer unprecedented versatility, performance and integration to support next generation devices,” said Andrew Cowell, senior vice president of Mobile Power Products at Intersil. “The ISL9590x PMICs enable ultrabooks with 360-degree hinges that for the first time allow users to rotate a touchscreen full circle to conceal the keyboard and use the system like a tablet. Manufacturers also have more space to add another Li-ion battery to further extend battery life.”
