UC3874N-2 Overview
With a 18-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Tube solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 4.4V~36V and has a 4.4V~36V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 300kHz. The Through Hole value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Soft Start. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. Various 18 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 12V volts. In addition to "UC3874", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 18 pins. Switching converter type is specifically Switching Regulator or Controllers. Because of DC switcher's Through Hole, it is suitable for most prototype designs and applications. DC regulator300kHz has the maximum frequency. A circuit should contain 36V in order to ensure the voltage regulator dc to dc runs safely and reliably. The output of this function is the greatest value of 1A. Because the dc switcher's maximum input voltage is 36V users must limit the voltage accordingly. In order to use a 4.5V voltage supply, switching controller is necessary to have one.
