 CHiL Semiconductor |
DIGITAL MULTIPHASE BUCK CONTROLLER The CHL8100 is a digital mixed-signal multiphase synchronous buck controller designed to power high performance microprocessors. It supports core voltage and load requirements for INTEL® VR11.1 and VR11.0 processors. This controller IC is intended for VR designs using up to four interleaved synchronous buck phases and capable of delivering up to 150A. The switching frequency of each phase can be digitally configured from 200 kHz up to 1 MHz. The CHL8100 utilizes non-volatile memory (NVM) to store device operating parameters. Designers can access, modify and store the parameters using the CHiL Intuitive Power Designer (IPD) GUI via the industry standard SMBUS interface. This reduces design op... |
