Description
The IR3826 is an easy-to-use, fully integrated and highly efficient dc-dc regulator. The onboard PWM controller and Opti MOS™ FETs with integrated bootstrap diode make the IR 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 300 k Hz to 1.5 MHz, and providing three selectable over current limits.
It also Features important protection functions, such as pre-bias start-up, thermally pensated current limit, over voltage protection and thermal shutdown to give required system level security in the event of fault conditions.
