Digital Multi-Phase Buck Controller

CHL8314

FEATURES

DESCRIPTION



Intel VR11.x compliant Digital PWM Controller

The CHL8314 is a 4-phase digital synchronous buck

controller for core regulation of high-performance Intel®

VR11.1 and VR11.0 platforms. The CHL8314 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 4-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 CHL8314 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 CHL8314 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

CHL8314 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 CHL8314 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 CHL8314 based

VRs. The controller includes a unique sensorless and

lossless input current monitoring capability.
