New Integrated POL Increases Efficiency for High-density Applications.
The new OptiMOS™ IR3826(A)M integrated point-of-load DC-DC regulator is a fully integrated and highly efficient device 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 5-16V and provide up to 16A (IR3826AM) or 23A (IR3826M) continuous current. It enables high-density (up to 1.5 MHz) operations with enhanced efficiency and reduced power losses and solves the heat challenge without or with minimum airflow in thermally constrained application designs.
The IR3826 is an easy-to-use, fully integrated and highly efficient DC-DC regulator.
The onboard PWM controller and OptiMOS MOSFETs with integrated bootstrap diode make the IR3826 a small footprint solution, providing high-efficiency power delivery.
The IR3826 is a versatile regulator, operating with wide input and output voltage range, offering programmable switching frequency from 300kHz to 1.5MHz, and providing three selectable over current limits.
It also features important protection functions, such as pre-bias start-up, thermally compensated current limit, over-voltage protection, and thermal shutdown to give required system-level security in the event of fault conditions.
