DESCRIPTION
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 |2C/SMBus/PMBus and
then selected using a 2-bit parallel bus for fast access.
The CHL82256/8G 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 CHL82256/8G
can be configured to enter 1-phase operation and active
diode emulation based upon load current or by command.
IR's unique Adaptive Transient Algorithm (ATA), based on
proprietary non-Iinear digital PWM algorithms, minimizes
output bulk capacitors.
The |2C/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.
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.
