Overclocked & Gaming platforms
DESCRIPTION
The IR3536A and IR3538A are dual-loop digital multi-phase
buck controllers. The IR3536A drive up to 6 phases and the
IR3538A drives up to 8 phases. The IR3536A and IR3538A
are fully Intel® VR12 and AMD® SVI/PVI compliant on both
loops and provide a Vtt tracking function for DDR memory.
The IR3536A and IR3538A 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 IR3536A and IR3538A can be configured to enter 1-
phase operation and active 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.
The I2C/PMBus interface can communicate with up to 16
IR3536A and IR3538A 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.
The IR3536A and IR3538A provides extensive OVP, UVP,
OCP and OTP fault protection and includes thermistor
based temperature sensing with VR_HOT signal.
NVM storage saves pins and enables a small package size.
The IR3536A and IR3538A 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.
