Description

The P8911 is a power management IC (PMIC) designed for

notebook, desktop, and embedded computing platforms. IDT’s

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 versus the P8900, the P8911 also features

power delivery characteristics tailored toward smaller form factor

memory modules that reside in systems that may operate on

battery power for extended periods.
