UC3874N-2 Overview
With a 18-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control has a supply voltage and operating voltage of 4.4V~36V. Qualified to work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 300kHz. Through Hole makes it suitable for general dc dc regulator. Soft Start provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 18 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. The dc to dc regulator is limited to 36V input voltage. Whenever the current value is 1A, switching converter outputs the highest possible value.
