Buck Regulator with PMBus Interface _IR38063
FEATURES
DESCRIPTION
 Internal LDO allows single 21V operation
The IR38063 PMBus SupIRBuck™ is an easy-to-use,
 Output Voltage Range: 0.5V to 0.875*PVin
 0.5% accurate Reference Voltage
fully integrated and highly efficient DC/DC regulator
with I2C/PMBus interface. The onboard PWM controller
and MOSFETs make IR38063 a space-efficient
 Programmable Switching Frequency up to 1.5 ^{solution, providing accurate power delivery for low}
MHz using Rt/Sync pin or PMBus
output voltage and high current applications.
 Internal Soft-Start with Pre-Bias Start-up
The IR38063 can be comprehensively configured via
 Enable input with Voltage Monitoring Capability _{PMBus and the configuration stored in internal}
 Remote Sense Amplifier with True Differential ^{memory. In addition, PMBus commands allow run-time}
Voltage Sensing
control, fault status and telemetry.
 Fast mode I2C and 400 kHz PMBus interface
 Sequencing and tracking capable
 Selectable analog mode or digital mode
The IR38063 can also operate as a standard analog
regulator without any programming and can provide
current and temperature telemetry in an analog format.
 66 PMBus commands for configuration, control,
fault protection and telemetry.
 Thermally compensated current limit with
configurable overcurrent responses
APPLICATIONS
 Optional light load efficiency mode
Server Applications
 External synchronization with Smooth Clocking
Netcomm applications
 Dedicated output voltage sensing protection
which remains active even when Enable is low.
Embedded telecom Systems
 Integrated MOSFETs and Bootstrap diode
Distributed Point Of Load Architectures
 Operating junction temp: -40^oC<Tj<125^oC
 Small Size 5mmx7mm PQFN
 Pb-Free (RoHS Compliant)
