SGM61412AXTN6G/TR

SGM61412AXTN6G/TR is a high frequency, synchronous buck converter with integrated switch. It can deliver up to 1.2A to the output over a wide input voltage range of 4.5V to 42V. It is suitable for various industrial applications with high input voltage or for power conditioning from unregulated sources. Moreover, the low 55µA quiescent current and ultra-low shutdown current of only 1.2µA makes the device suitable choice for battery-powered applications. SGM61412 features high efficiency over a wide load range achieved by scaling down the switching frequency at light load condition to reduce switching and gate driving losses. Other features include internal compensation, internal monotonic soft-start even with pre-biased output and fast loop response due to the peak-current mode controller. Application includes high voltage power conversions, industrial power systems, distributed power systems, battery powered systems, power meters.
