UC3874DW-1 Overview
The switching controller fits in the 18-SOIC (0.295, 7.50mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tube is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 9V~36V. Work well in dc switchers with a 0°C~70°C TA. The switching controller is capable of switching at the Up to 300kHz position. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 18. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. The output of this function is the greatest value of 1A.
