Multiphase Controllers
Status: New
The AOZ98252QI is a high-performance digital, low quiescent current, multiphase buck controller which provides two output power rails in a M+N = 8 phase configuration and is designed to power AMD SVI3 processors, ASICs, SoCs, and FPGAs. Output VR1 can be configured up to 8 phases and output VR2 can be configured between 0 and 4 phases.
