25A Single-input Voltage, Synchronous Buck Regulator with PMBus Interface

Overview

TopologyBuck Converter
Input voltage5.5-21 V
Switching frequency225-1650 kHz
IC revision3.13

Description

The IR38063 PMBus SupIRBuck™ is an easy-to-use, fully integrated and highly efficient DC/DC regulator with I2C/PMBus interface. The onboard PWM controller and MOSFETs make IR38063 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications.The IR38063 can be comprehensively configured via PMBus and the configuration stored in internal memory. In addition, PMBus commands allow run-time control, fault status and telemetry.The IR38063 can also operate as a standard analog regulator without any programming and can provide current and temperature telemetry in an analog format.
