The IR38164 family offers either full SVID (Serial Voltage ID) compatibility or 3-bit PVID (Parallel Voltage ID) flexibility and takes advantage of Infineon’s OptiMOS MOSFETs. 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.

With its integrated SVID, in the smallest size available in its class, IR38164 offers 50 percent space saving compared to traditional externally powered digital controller solutions. The product also provides enhanced current monitoring accuracy. IR38164 has a 5 mm x 7 mm Cu-clip package awith an efficiency of greater than 91 percent for core rail (0.7 V-1.2 V) efficiency, and higher than 97 percent for 5 V out efficiency. The efficiency also allows the IR38164 to support high frequency operations, up to 30 A, from the improved thermal characteristics, as well as enabling high current 3.3 V and 5 V output voltages delivery at high ambient temperature with minimum airflow.
The IR38164 uses Infineon’s third generation voltage mode PWM engine. This enables high control bandwidth, 50 percent 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.
