Infineon Technologies IR38060 PMBus SupIRBuck™ DC-DC Regulators

Infineon Technologies IR38060 PMBus SupIRBuck™ DC-DC Regulators are highly integrated 6A single-input voltage, synchronous buck regulators with an I²C PMBus interface. The IR38060 series also integrates a PWM controller and MOSFETs, providing a highly space-efficient solution with accurate power delivery for low-output-voltage and high-current applications. The devices 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 modules also operate as a standard analog regulator without any programming and can provide current and temperature telemetry in an analog format. Infineon IR38060 PMBus SupIRBuck DC-DC Regulators are offered in a compact 5mm x 6mm PQFN-26 package, ideal for space-constrained applications.
