SGM61410XN6G/TR

SGM61410XN6G/TR is a 1.2MHz, 600mA, 42V synchronous buck converter. It is a high-frequency, synchronous buck converter with integrated switches. It is suitable for various industrial or automotive applications with high input voltage or for power conditioning from unregulated sources. It features high efficiency over a wide load range achieved by scaling down the switching frequency at light loads 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. Protection features include current limiting and short-circuit protection, thermal shutdown with auto recovery and output over-voltage protection. Frequency fold-back helps prevent inductor current runaway during start-up. Applications include high voltage power conversions, automotive systems, industrial and distributed power system, battery powered systems, power meters.
