IR3564B
IR3570B
Dual Output Digital Multi-Phase Controller
FEATURES
DESCRIPTION
Dual output 4+1 and 3+2 phase PWM
The IR3564B/70B is a dual-loop digital multi-phase buck
controller designed for CPU voltage regulation and is fully
compliant with AMD® SVI1 & SVI2 and Intel® VR12 &
VR12.5 specifications.
Controllers
Easiest layout and fewest pins in the industry
Fully supports AMD® SVI1 & SVI2 with dual
OCP and Intel® VR12 & VR12.5
The IR3564B/70B includes IR’s Efficiency Shaping
Technology to deliver exceptional efficiency at minimum
cost across the entire load range. IR’s 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.
Complies with VR12.5 Rev 1.3 requirement
for SVID register 15h to have <200 µSec
filter
Overclocking & Gaming Mode
Switching frequency from 200kHz to 2MHz
per phase
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.
IR Efficiency Shaping Features including
Dynamic Phase Control and Automatic Power
State Switching
IR Adaptive Transient Algorithm (ATA) on
both loops minimizes output bulk capacitors
and system cost
Auto-Phase Detection with auto-
The IR3564B/70B provides extensive OVP, UVP, OCP
and OTP fault protection and includes thermistor based
temperature sensing with VRHOT signal.
compensation
Per-Loop Fault Protection: OVP, UVP, OCP,
OTP, CFP
The IR3564B/70B includes numerous features like
register diagnostics for fast design cycles and platform
differentiation, simplifying VRD design and enabling
fastest time-to-market (TTM) with “set-and-forget”
methodology.
I2C/SMBus/PMBus system interface for
