DESCRIPTION
The CHL8102/03/04 are dual-loop digital multi-phase buck
controllers designed for CPU voltage regulation. The
CHL8113 is a single-loop digital multiphase buck controller
ideal for Server DDR memory voltage regulation. They are
fully compliant with the Intel® VR12 and AMD® SVI
(CHL8103/04) specifications.
size. Device configuration and fault parameters are easily
defined using the CHiL Intuitive Power Designer (IPD) GUI
and stored in on-chip MTP.
The CHL8102/03/04/13 provides extensive OVP, UVP, OCP
and OTP fault protection and the CHL8103/04/13 includes
thermistor based temperature sensing with VRHOT signal.
The CHL8102/03/04/13 includes numerous features like
register diagnostics for fast design cycles and platform
differentiation, truly simplifying VRD design and enabling
fastest time-to-market (TTM) with “set-and-forget”
methodology.

The CHL8102/03/04/13 include CHiL Efficiency Shaping
Technology to deliver exceptional efficiency at minimum
cost across the entire load range. CHiL Dynamic Phase
Control adds/drops active phases based upon load current
and can be configured to enter 1-phase operation and 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 and Multiple Time Programmable
(MTP) storage saves pins and enables a small package
