Overview

The P8911 is a power management IC (PMIC) designed for notebook, desktop, and embedded computing platforms. This device enables next-generation client platforms to take full advantage of DDR5 memory to realize greater performance, density, and reliability while reducing overall system power. With over 50% reduction in package footprint vs. P8900, the P8911 features power delivery characteristics tailored towards smaller form factor memory modules that reside in systems that may operate on battery power for extended periods.
