IR3536/38
Digital Multi-Phase Buck Controller
FEATURES
DESCRIPTION
6-phase & 8-phase dual output PWM Controller
The IR3536/CHL8326 and IR3538/CHL8328 are dual-loop
digital multi-phase buck controllers. The IR3536/CHL8326
drive up to 6 phases and the IR3538/CHL8328 drives up to
8 phases. The IR3536/CHL8326 and IR3538/CHL8328 are
fully Intel® VR12 and AMD® SVI/PVI compliant on both
loops and provide a Vtt tracking function for DDR memory.
Phases are flexibly assigned between Loops 1 & 2
Intel® VR12, AMD® 3.4MHz SVI/PVI & Memory
modes
Overclocking & Gaming Mode with Vmax setting
Switching frequency from 200kHz to 1.2MHz per
phase
The IR3536/CHL8326 and IR3538/CHL8328 include 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 based on real-time load current. IR Dynamic Phase
Control adds/drops phases based upon load current.
The IR3536/CHL8326 and IR3538/CHL8328 can be
configured to enter 1-phase operation and active diode
emulation mode automatically or by command.
IR Efficiency Shaping Features including Variable
Gate Drive and 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) on both loops
minimizes output bulk capacitors and system cost
Auto-Phase Detection with auto-compensation
IR’s unique Adaptive Transient Algorithm (ATA), based on
proprietary non-linear digital PWM algorithms, minimizes
output bulk capacitors.
Per-Loop Fault Protection: OVP, UVP, OCP, OTP, CFP
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
IR3536/CHL8326 and IR3538/CHL8328 based VR loops.
Device configuration and fault parameters are easily
defined using the IR Intuitive Power Designer (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; -20ºC to 85ºC ambient
operation
The IR3536/CHL8326 and IR3538/CHL8328 provides
extensive OVP, UVP, OCP and OTP fault protection and
includes thermistor based temperature sensing with
VR_HOT signal.
Pb-Free, RoHS, 7x7 48-pin & 8x8 56-pin QFN, MSL2
package
APPLICATIONS
NVM storage saves pins and enables a small package size.
The IR3536/CHL8326 and IR3538/CHL8328 also include
numerous features like register diagnostics for fast design
cycles and platform differentiation, truly simplifying
VRD design and enabling fastest time-to-market with its
“set-and-forget” methodology.
