Fully integrated SVID and PVID enables voltage regulator efficiency
The latest Integrated Point-of-Load (IPOL) family has been announced by Infineon Technologies. It combines ease of use with high power density. According to the company, it is the industry’s first fully integrated regulator offering PMBUS, SVID and PVID functionality for powering Intel CPU POL rails, chipsets and ASIC/FPGA. With 50% space saving compared to alternative external power solutions, this is the smallest solution size of its class.
The IR38163/5 and IR38363/5 are tailored for powering Intel V ccio and V cmp 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.
IR38263/5 offers 3-bit parallel VID (PVID) for powering Intel chipset P VNN rails and FPGA. It is suitable for Telecom applications which require constant frequency operation, and NetCom and Storage applications that require extensive PMBus, accurate V out, and ultra low ripple.
This family of IPOL devices takes advantage of the benchmark efficiency of the OptiMOS™ 5. Additionally, the small 7x7mm 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 PWM engine which provides ultra low ripple and jitter. They minimise noise and increase control bandwidth while requiring fewer capacitors than other design options. True differential voltage sensing, wide margining range and a 0.5 % V ref accuracy work together to deliver a V out accuracy greater than 1%.
With the introduction of an end-to-end Enterprise power family, Infineon’s full solution includes smart digital controllers and high performance IPOL and Power Stages.
