Description
The IR3826 is an easy-to-use, fully integrated and highly efficient dc-dc regulator. The onboard PWM controller and OptiMOS™ FETs with integrated bootstrap diode make the IR a smal 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 kHz to 1.5 MHz, 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.
