IR3541

CHL8325A/B

Digital Multi-Phase Buck Controller

FEATURES

DESCRIPTION



5-phase dual output PWM Controller

The IR3541 and CHL8325A/B are dual-loop digital

multi-phase buck controllers that drive up to 5 phases.

The IR3541 and CHL8325A/B are fully Intel® VR12 and AMD®

SVI compliant on both loops and provides a Vtt tracking

function for DDR memory.

Phases are flexibly assigned between Loops 1 & 2

Intel® VR12, AMD® 400kHz & 3.4MHz SVI and

Memory modes



Dual OCP support for I-spike enhanced AMD CPUs

SMB_Alert Pin for Servers

NVM storage saves pins and enables a small package size.

PMBus Address pin or Variable Gate Drive

2^ndTemperature Sense for VR12 Desktop

(CHL8325B)

The IR3541 and CHL8325A/B 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 as a function

of real-time load current. IR Dynamic Phase Control

adds/drops active phases based upon load current.

The IR3541 and CHL8325A/B can be configured to enter

1-phase operation and active diode emulation mode

automatically or by command.



Overclocking & Gaming Mode with Vmax setting

Switching frequency from 200kHz to 1.2MHz per

phase



IR Efficiency Shaping Features including Variable

Gate Drive (IR3541/CHL8325A only) and Dynamic

Phase Control

IR’s unique Adaptive Transient Algorithm (ATA), based on

proprietary non-linear digital PWM algorithms, minimizes

output bulk capacitors.



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

The I2C/PMBus interface can communicate with up to 16

IR3541 and CHL8325A/B 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.



Auto-Phase Detection with auto-compensation

Per-Loop Fault Protection: OVP, UVP, OCP,

OTP, CFP

The IR3541 and CHL8325A/B 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.



I2C/SMBus/PMBus system interface for telemetry

of Temperature, Voltage, Current & Power for

both loops

Non-Volatile Memory (NVM) for custom

configuration



Compatible with IR ATL and 3.3V Tri-state Drivers

PIN DIAGRAM

+3.3V supply voltage; -20ºC to 85ºC ambient

operation



Pb-Free, RoHS, 6x6 40-pin QFN, MSL2 package

APPLICATIONS



Intel ® VR12 & AMD® SVI based systems

DDR Memory with Vtt tracking

Overclocked & Gaming platforms
