OptiMOS™ IPOL DC-DC Converters

Infineon Technologies OptiMOS™ IPOL DC-DC Converters, featuring a digital interface, are integrated solutions with comprehensive PMBus telemetry and control, and parallel VID and SVID support for Intel based systems. This makes these devices ideal for high-density smart enterprise systems. The onboard PWM controller and OptiMOS MOSFETs provide accurate power delivery for low output voltage and high current applications. The IR381x and IR383x devices are tailored for powering Intel Vccio and Vcmp rails, and Intel-based server applications that require SVID support. The devices do not require pre-programming as they are pre-configured for Intel requirements and addresses.
