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 ICRITICAL signal
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
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.
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
(CHL8203/13/14)
