Infineon Technologies OptiMOS™ IPOL DC-DC Converters

Infineon Technologies OptiMOS™ IPOL DC-DC Converters, featuring a digital interface, are integrated solutions featuring 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 aare tailored for powering Intel Vccio and Vcmp rails, and Intel-based Server applications which require SVID support. The devices do not require pre-programming as they are pre-configured for Intel requirements and addresses.

The IR382x device offers 3-bit parallel VID (PVID) for powering Intel chipset PVNN rails and FPGA. It is ideal for Telecom applications which require constant frequency operation, and NetCom and Storage applications that require extensive PMBus, accurate Vout, and ultra-low ripple.

The OptiMOS IPOL devices take advantage of the benchmark efficiency of the OptiMOS 5. Additionally, the small 5mm x 7mm PQFN package with Cu clip allows the devices to operate at up to 30A, at high frequency with minimal airflow. Pin compatible options are available with and without PMBus support. The family features Infineon’s state-of-the-art PWM engine which provides ultra-low ripple and jitter. They minimize noise and increase control bandwidth while requiring fewer capacitors than other design options. True differential voltage sensing, wide margining range and a 0.5% Vref accuracy work together to deliver a Vout accuracy greater than 1%
