6A Single-input Voltage, Synchronous Digital SupIRBuck
Buck Regulator with PMBus Interface IR38060
FEATURES
DESCRIPTION
Internal LDO allows single 21V operation
The IR38060 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 IR38060 a space-efficient
Programmable Switching Frequency up to solution, providing accurate power delivery for low
1.5MHz using Rt/Sync pin or PMBus
output voltage and high current applications.
Internal Soft-Start with Pre-Bias Start-up
The IR38060 can be comprehensively configured via
Enable input with Voltage Monitoring Capability PMBus and the configuration stored in internal
Remote Sense Amplifier with True Differential
Voltage Sensing
memory. In addition, PMBus commands allow run-time
control, fault status and telemetry.
Fast mode I2C and 400 kHz PMBus interface
Sequencing and tracking capable
Selectable analog mode or digital mode
The IR38060 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
configurable overcurrent responses
