Digital Multi-Phase Buck Controller

CHL8203/12/13/14

FEATURES

DESCRIPTION



Dual output 2/3/4+1-phase PWM Controller

(CHL8212/13/14) and single output 3-phase PWM

Controller (CHL8203)

The CHL8212/13/14 are dual-loop digital multi-phase

buck controllers and the CHL8203 is a single-loop digital

multiphase buck controller designed for GPU voltage

regulation. Dynamic voltage control is provided by

registers which are programmed through I2C and then

selected using a 3-bit parallel bus for fast access.



Easiest layout and fewest pins in the industry

Footprint compatible with CHL8225 (CHL8213/14)

for analog and power signals



Up to 3 VID select lines for dynamic voltage

transitions

The CHL8203/12/13/14 include IR Efficiency Shaping

Technology to deliver exceptional efficiency at minimum

cost across the entire load range. IR 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.

Slow OCP for Thermal Design Current (TDC)

protection



Programmable I_CRITICALsignal

I2C interface for configuration & telemetry

Pin programmable I2C address (CHL8203/13/14)

IR’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 size.

Device configuration and fault parameters are easily

defined using the IR Digital Power Design Center (DPDC)

GUI and stored in on-chip MTP.

Overclocking support with I2C voltage override and

Vmax setting



Flexible I2C bus security features

I2C security enable pin (CHL8203/13/14)

Independent loop switching frequencies from 200kHz

to 1.2MHz per phase

The CHL8203/12/13/14 provides extensive OVP, UVP, OCP

and OTP fault protection and the CHL8203/13/14 includes

thermistor based temperature sensing with VRHOT signal.



IR Efficiency Shaping with Dynamic Phase Control

(DPC)

1-phase & Active Diode Emulation modes for light

load efficiency

The CHL8203/12/13/14 includes numerous features like

differentiation, truly simplifying VRD design and enabling

fastest time-to-market (TTM) with “set-and-forget”

methodology.

IR Adaptive Transient Algorithm (ATA) on both loops

minimizes output bulk capacitors and system cost



Per-Loop Fault Protection: OVP, UVP, OCP

Thermal Protection (OTP) and VRHOT# flag
