Infineon Technologies has introduced the new OptiMOS IR3826(A)M integrated point-of-load DC/DC voltage regulator. It is a fully integrated and highly efficient device in two versions (IR3826AM for 16A and IR3826M for 23A) for applications such as netcom router and switches, datacom, telecom base stations, server and enterprise storage.

The voltage regulator can operate from an input voltage of 12V (five to 17V) and provide up to 16 or 23A continuous current. It enables high-switching-frequency operations with enhanced efficiency and reduced power losses compared to previous generations of Infineon’s offering. Furthermore, the device supports high switching frequency of up to 1.5MHz for small PCB size and less capacitors.

Both current ratings are offered in PQFN package with five by six millimetre footprint for easy scalability. Parts are pin-compatible to the previous product offerings to allow risk-free efficiency upgrade with minimum design effort.

The IR3826(A)M solves the heat challenge without or with minimum airflow in thermally constrained application designs such us 3.3 or 5V supply voltages. Additionally, it supports applications that operate with high ambient temperature, e.g., 85˚C for telecom.

The PWM Gen 3 engine of the devices allows operation with fixed frequency to reduce noise in multi-rail telecom or high-end Netcom applications, like base stations.

The devices are fully RoHS2 compliant without an exemption to accommodate future regulations.

High volume production has started. Evaluation boards are also available.
