The SGM61412 is a high frequency, synchronous Buck converter with integrated switches. 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 make it a 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. Switching at 1.2MHz, the SGM61412 can prevent EMI noise problems, such as the ones found in AM radio, ADSL and PLC applications.

Protection features include current limit and short-circuit protection, thermal shutdown with auto recovery and output over-voltage protection. Frequency fold-back helps prevent inductor current runaway during startup.

The SGM61412 is available in a Green TSOT-23-6 package. It operates over a wide ambient temperature range of -40 to +125.
