Digital Multi-Phase Buck Controller  
CHL8225G/8G  
FEATURES  
DESCRIPTION  
5-phase & 8-phase dual output PWM Controller  
The CHL8225G/8G are dual-loop, digital multi-phase buck  
controllers. The CHL8225G drives up to 5 phases and the  
CHL8228G drives up to 8 phases. They feature Input  
Voltage Management allowing up to 3 input voltages to be  
monitored to ensure adequate power is delivered to the  
load. Dynamic voltage control is provided by 4 registers  
which are programmed through I2C/SMBus/PMBus and  
then selected using a 2-bit parallel bus for fast access.  
with phases flexibly assigned between Loops 1 & 2  
Dynamic voltage control by 2-bit parallel interface  
with Gamer Mode override and Vmax setting  
Input Voltage Management for up to 3 Input  
Voltages  
ICRITICAL Monitor and Phase Current Capture Mode  
Phase Switching frequency from 200kHz to 1.2MHz  
The CHL8225G/8G includes the IR Efficiency Shaping  
Technology to deliver exceptional efficiency at minimum  
cost across the entire load range. IR Variable Gate Drive  
optimizes the MOSFET gate drive voltage as a function of  
real-time load current. IR Dynamic Phase Control adds and  
drops phases based upon load current. The CHL8225G/8G  
can be configured to enter 1-phase operation and active  
diode emulation based upon load current or by command.  
IR Efficiency Shaping Features including Variable  
Gate Drive, Dynamic Phase Control  
Programmable 1-phase or 2-phase for Light Loads  
and Active Diode Emulation for Very Light Loads  
IR Adaptive Transient Algorithm (ATA) minimizes  
output bulk capacitors and system cost  
Per-Loop Fault Protection: OVP, UVP, OCP, OTP  
IR’s unique Adaptive Transient Algorithm (ATA), based on  
proprietary non-linear digital PWM algorithms, minimizes  
output bulk capacitors.  
I2C/SMBus/PMBus system interface for telemetry of  
Temperature, Voltage, Current & Power for both  
loops  
The I2C/PMBus interface can communicate with up to 16  
CHL8225G/8G-based VR loops. Device configuration and  
fault parameters are defined using the IR Digital Power  
Design Center (DPDC) GUI and stored in on-chip NVM.  
Non-Volatile Memory (NVM) for custom  
configuration  
Compatible with IR ATL and 3.3V tri-state Drivers  
+3.3V supply voltage; 0ºC to 85ºC ambient  
operation  
The CHL8225G/8G provides extensive OVP, UVP, OCP and  
OTP fault protection and includes thermistor based  
temperature sensing with VRHOT signal. The CHL8225G/8G  
includes numerous features like register diagnostics for  
fast design cycles and platform differentiation, simplifying  
VRD design and enabling fastest time-to-market with its  
“set-and-forget” methodology.
