CHL8328-21CRT Description
The CHL8328-21CRT is a dual-loop digital multi-phase buck controller. The CHL8328-21CRT drives up to 8 phases. The CHL8328-21CRT is fully Intel? VR12 and AMD? SVI/PVI compliant on both loops and provides a Vtt tracking function for DDR memory. The CHL8328-21CRT includes the IR Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Variable Gate Drive optimizes the MOSFET gate drive voltage based on real-time load current.
