Product Summary

The NCP3170ADR2G is a Switching Converter. The NCP3170ADR2G is a flexible synchronous PWM Switching Buck Regulator. The NCP3170ADR2G operates from 4.5 V to 18 V, sourcing up to 3 A and is capable of producing output voltages as low as 0.8 V. The NCP3170ADR2G also incorporates current mode control. To reduce the number of external components, a number of features are internally set including soft start, power good detection, and switching frequency. The NCP3170ADR2G is currently available in an SOIC-8 package. The applications of the NCP3170ADR2G include Set Top Boxes, LCD Monitors and TVs, Cable Modems, PCIe Graphics Cards, Telecom/Networking/Datacom Equipment and Point of Load DC/DC Converters.
