| Infineon IR38164 DC-DC POL Converter
| Provides SVID compatibility and 3-bit PVID flexibility
| Also supports PMBus functionality for POL rails

Power density is critical in space-constrained storage, network communications, server, and telecom designs. Infineon Technologies announced on the 26th the launch of the highly integrated IR38164 DC-DC POL converter.

The Infineon IR38x6x family offers full SVID compatibility or 3-bit PVID flexibility, making it easy to design and support Intel CPU and chipset POL rails in Intel systems. Some products also support PMBus functionality for POL rails requiring control, telemetry, and voltage configuration in applications such as telecom base stations, networking, and storage SSDs. This POL family leverages the high efficiency of OptiMOS MOSFETs.
The IR38164, the smallest in its class with built-in SVID, saves up to 50% space compared to conventional externally driven digital controller solutions and provides improved current monitoring accuracy.

The IR38164 is housed in a 5mm x 7mm copper clip package and adopts OptiMOS 5, which has the lowest RDS(on), FOM (figure of merit), and QRR on the market, achieving over 91% core rail (0.7V to 1.2V) efficiency and over 97% 5Vout efficiency.

The IR38164, with its excellent thermal characteristics, can operate at high frequencies up to 30 A. By adopting advanced packaging and high-performance MOSFETs, it can deliver high-current 3.3 V and 5 V output voltages at high ambient temperatures with minimal airflow.

The IR38164 employs Infineon's third-generation voltage-mode PWM engine, enabling high control bandwidth, 50% smaller capacitors, and stable 1MHz operation. It combines true differential voltage detection, wide margining range, and 0.5% Vref accuracy, resulting in better than 1% Vout accuracy.

IR38x6x products are programmed for Intel VR13 rails, including VCCIO, VMPC, and PVNN rails. They are pin-compatible with products that support or do not support PMbus functionality.
