An Integrated Point-of-Load (IPOL) family combines ease-of-use with high power density. It is said to be the industry’s first fully integrated regulator offering PMBUS, SVID and PVID functions for powering Intel CPU POL rails, chip-sets and ASIC/FPGA. With 50% space saving compared to alternative external power solutions, this is said to be the smallest solution size of its class.
The IR38163/5 and IR38363/5 are 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.
IR38263/5 offers three-bit parallel VID (PVID) for powering Intel chipset P VNN rails and FPGA. It is ideal 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 7×7-mm PQFN package with Cu clip allows the devices to operate at up to 30 A, 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 % V ref accuracy work together to deliver a Vout 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.
Samples are available now and the devices are in production. More information is available at www.infineon.com/optimos_digital_ipol.
