A fully integrated and highly efficient device, it comes in two versions (IR3826AM for 16A and IR3826M for 23A) for applications such as netcom routers and switches, datacom, telecom base stations, server and enterprise storage.
The voltage regulator can operate from an input voltage of 12V (5V to 17V) and provide up to 16A or 23A continuous current. It enables high-switching-frequency operations with enhanced efficiency and reduced power losses compared to previous device generations.. In addition, it 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 5 mm x 6 mm 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 has been designed to address the heat challenge without or with minimum airflow in thermally constrained application designs such us 3.3V 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.
