UC3874N-1G4 Product Details

UC3874N-1G4 Overview


It comes in the 18-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 9V~36V volts and has 9V~36V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to Up to 300kHz. The Through Hole allows it to be used for dc dc regulator in general. For efficient switching control, the dcdc regulator features Soft Start. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 18 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. You can find other relevant dc to dc converter ics by searching "UC3874". 18 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. At most, the dc to dc regulator accepts 36V input voltage. 300kHz is the maximum frequency of this dc regulators. A maximum value of 1A is output for current.
