The CHL8326/8 are dual-loop digital multi-phase buck controllers. The CHL8326 drives up to 6 phases and the CHL8328 drives up to 8 phases. The CHL8326/8 is fully Intel® VR12 and AMD® SVI/PVI compliant on both loops and provides a Vtt tracking function for DDR memory. NVM storage saves pins and enables a small package size. The CHL8326/8 includes the CHiL Eff.
