Digital Multi-Phase Buck Controller
CHL8316
FEATURES
DESCRIPTION
Intel VR11.x compliant Digital PWM Controller
The CHL8316 is a 6-phase digital synchronous buck
controller for core regulation of high-performance Intel®
VR11.1 and VR11.0 platforms. The CHL8316 is fully
compliant with VR11.1 including Power Status Indicator
(PSI) and for improved light load efficiency and accurate
current output (IMON).
Programmable 1-phase to 6-phase operation
Customized Digital Over-Clocking features an
easy-to-use SMBus Gamer command and a Gamer
VID control up to 2.3V, Gamer Vmax, VID Override
or Track, Digital Load-Line Adjust, Gamer OC/OVP,
Gamer OFF pin and Gamer OTP
The CHL8316 includes a customized set of digital over-
clocking features which require no external components.
Gaming applications can use the SMBus interface to place
the VRD into “Gamer Mode” to extend VID up to 2.3V with
6.25 mV resolution.
IR Efficiency Shaping features a Variable Gate Drive
and Dynamic Phase Control
1-phase to 2-phase PSI for Light Loads
Adaptive Transient Algorithm minimizes capacitors
Enables Thermal Phase Balancing
The CHL8316 deploys a number of efficiency shaping
features such as variable MOSFET gate drive versus load,
programmable PSI modes for optimum light-load along
with programmable phase shedding to autonomously
add/drop phases versus load.
SMBus Fault Indicators: OVP, UVP, OCP, OTP
SMBus interface for configuring and monitoring;
SMBus commands include monitoring input
current and power
CHL8316 supports NTC temperature sense to report
temperature and trigger VR HOT and OTP faults. Digital
thermal balancing allows proportional current imbalance
between phases.
Compatible with IR ATL Drivers and tri-state Drivers
9 bytes of NVM storage available for customer use
+3.3V supply voltage; 0ºC to 85ºC Ambient
operation
The CHL8316 provides extensive OVP, UVP, OCP, and
OTP fault protection. Device and fault configuration
parameters are easily defined using the IR Power Designer
GUI and stored in on-chip non-volatile memory (NVM).
RoHS Compliant, MSL level 1 package
APPLICATIONS
Intel® VR11.x CPU VRD and VRM; DDR Memory
The 3-pin SMBus interface can be used to monitor a variety
of operating parameters on up to seven CHL8316 based
VRs. The controller includes a unique sensorless and
lossless input current monitoring capability.
