UC3874N-2G4 Overview
With its 18-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). dc controls with 4.4V~36V voltage are supplied and operated. 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. The Through Hole makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 18 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. A search for "UC3874" will reveal other relevant dc to dc converter ics. There are only 18 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. DC switcher's Through Hole qualifies it for most applications and prototypes. There is a maximum frequency of 300kHz for this dc regulators. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 36V. Whenever the current value is 1A, switching converter outputs the highest possible value. Since the dc switcher's maximum input voltage is 36V, the voltage must be regulated accordingly. A voltage of 4.5V must be present in the supply.
