UC3874N-1 Overview
Capsuled in the 18-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. dc motor controller is suitable for 1 output generation. Tube solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). This dc control operates at 9V~36V and has a 9V~36V supply voltage. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller can be switched at Up to 300kHz. A generalization of dc dc regulator can be made using Through Hole. To ensure efficient switching, this dcdc regulator features a Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of terminations with 18 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. UC3874 can be used to locate other relevant dc to dc converter ics. There are a total of 18 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. Considering the dc to dc regulator can only accept 36V input voltage, it is important to take note of this. DC regulator's maximum frequency is 300kHz. A value of 1A is output as the maximum value of current.
