New Power Management ICs Optimized for Intel's 6th-Generation Skylake Core Processor Architecture

The BD99991GW PMIC (Power Management ICs) supports the core power rails required by the Skylake platform and supports Intel's IMVP8 power management interface, while the BD99992GW is designed to provide the additional 10 power rails required for the rest of platform.

Compared with discretesolutions, ROHM's dual-PMIC chipset reduces the number of peripheral components by 18% and mounting area by 33%, contributing to greater space savings and increased system size reduction.
Matching the PMICs - which feature industry-leading power efficiency - with ROHM-optimized discrete components can enable further reduction in power consumption, mounting area, and number of external parts. READ MORE
