DESCRIPTION
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 Efficiency Shaping
Technology to deliver exceptional efficiency at minimum
cost across the entire load range. CHiL Variable Gate Drive
optimizes the MOSFET gate drive voltage based on real-
time load current. CHiL Dynamic Phase Control adds/drops
phases based upon load current. The CHL8326/8 can be
configured to enter 1-phase operation and active diode
emulation mode automatically or by command.
CHiL’s unique Adaptive Transient Algorithm (ATA), based
on proprietary non-linear digital PWM algorithms, minimizes
output bulk capacitors. In addition, a coupled inductor mode,
with phases added/dropped in pairs, enables further
improvement in transient response and form factor.
The I2C/PMBus interface can communicate with up to 16
CHL8326/8 based VR loops. Device configuration and fault
parameters are easily defined using the CHiL Intuitive
Power Designer (IPD) GUI and stored in on-chip NVM.
The CHL8326/8 provides extensive OVP, UVP, OCP and
OTP fault protection and includes thermistor based
