原装正品 SC8746 南芯同步降压-升压转换器

　　Descriptions

　　The SC8746 is a buck-boost converter with two low-side integrated power switches capable of regulating the output voltage at, above, or below the input voltage. The SC8746 operates over 3.7V to 36V wide input voltage and can output 1V to 22V voltage to support a variety of applications.

　　The SC8746 is suitable for USB power delivery application. It can work well with external USB PD controller through I2C interface and provide flexibility of programmable features.

　　The SC8746 employs current mode control scheme. The switching frequency could be set at 270kHz/405kHz/540kHz through I2C. The SC8746 also provides optional spread spectrum to optimize EMI performance.

　　The SC8746 offers output over-voltage protection, cycle-by-cycle current limit, output short circuit protection, average output current limit and thermal shutdown protection

　　The SC8746 is available in 20-pin 3mm X 5mm Wettable Flank QFN packages.
