SGM61410Q.pdf

The SGM61410Q is a high frequency, synchronous Buck converter with integrated switches. It can deliver up to 600mA to the output over a wide input voltage range of 5V to 42V. The low 14µA quiescent current and ultra-low shutdown current of only 0.6µA make it a suitable choice for battery-powered applications. SGM61410Q 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_x0002_circuit protection, thermal shutdown with auto recovery and output over-voltage protection. Frequency fold-back helps prevent inductor current runaway during startup. This SGM61410Q is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications. SGM61410Q is available in a Green SOT-23-6 package.
