IR3564A
IR3570A
Dual Output Digital Multi-Phase Controller
FEATURES
DESCRIPTION
Dual output 4+1 and 3+2 phase PWM
Controllers
The IR3564A/70A 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
specifications.
Easiest layout and fewest pins in the industry
Fully supports AMD® SVI1 & SVI2 with dual
OCP and Intel® VR12
Overclocking & Gaming Mode
Switching frequency from 200kHz to 2MHz
per phase
IR Efficiency Shaping Features including
Dynamic Phase Control and Automatic Power
State Switching
Programmable 1-phase operation for Light
Loads and Active Diode Emulation for Very
Light Loads
IR Adaptive Transient Algorithm (ATA) on
both loops minimizes output bulk capacitors
and system cost
Auto-Phase Detection with autocompensation
Per-Loop Fault Protection: OVP, UVP, OCP,
OTP, CFP
I2C/SMBus/PMBus system interface for
telemetryof Temperature, Voltage, Current &
Power for both loops
Multiple Time Programming (MTP) with
integrated charge pump for easy custom
configuration
Compatible with IR ATL and 3.3V tri-state
Drivers
+3.3V supply voltage; -40°C to 85°C ambient
operation
The IR3564A/70A 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.
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.
The IR3564A/70A provides extensive OVP, UVP, OCP
and OTP fault protection and includes thermistor based
temperature sensing with VRHOT signal.
The IR3564A/70A 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.
