IR3826IR 8 OptiMOS™ IPOL 23 A single-voltage synchronous Buck regulatorFeatures Single 5 V to 17 V application or Wide Input Voltage Range from 1.0 V to 17 V with external Vcc Precision Reference Voltage (0.6 V ± 0.6%) for Output Voltage Range: 0.6 V to 0.86×Vin Enhanced Line/Load Regulation with Feed-Forward Programmable Switching Frequency up to 1.5 MHz Monotonic Start-Up with Internal Digital Soft-Start & Enhanced Pre-Bias Start-Up Thermally Compensated Internal Over-Current Protection with Three Selectable Settings Enable input with Voltage Monitoring Capability & Programmable Power Good Output Thermal Shut Down Operating temp: -40 °C < Tj < 125 °C Small Size: 6 mm x 5 mm PQFN Lead-free, Halogen-free and RoHS2 Compliant Potential applications Server Applications Storage Applications Telecom & Datacom Applications Distributed Point of Load Power Architectures Product validation Qualified for industrial applications according to the relevant tests of JEDEC47/20/22 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.
