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