Fully Integrated Voltage Regulator Solution With Intel SVID & PMBus


Power density is key in latest space constrained storage, netcom , servers and telecom designs

Infineon Technologies introduces the newest member of its integrated point-of-load product family, the IR38164 DC-DC POL converter. Infineon’s IR38x6x family offers either full SVID compatibility or 3-bit PVID flexibility.

This makes it easy to design and support Intel CPU and chipset POL rails in Intel systems. Some products support PMBus functionality for POL rails requiring control, telemetry, voltage settings in applications such as telecom base stations, networks and storage SSDs. This family of IPOL devices takes advantage of the benchmark efficiency of the OptiMOS™ MOSFET.


IR38164 has a 5 mm x 7 mm Cu-clip package and OptiMOS 5 with the lowest R DS(on), FOM (figure of merit), and Q RR attributes in the market. Thus, enabling greater than 91% for core rail (0.7 V-1.2 V) efficiency, and higher than 97% for 5 V out efficiency.

High control bandwidth, 50% fewer capacitors and stable 1 MHz operations. True differential voltage sensing, wide margining range and a 0.5 percent V ref accuracy work together to deliver a V out accuracy greater than 1 percent.

The IR38x6x products are programmed for Intel VR13 rails, such as V CCIO, V MPC and P VNN rails. Pin compatible options are available with and without PMBus support.
