UC3874DWTR-1 Overview
Capsuled in the 18-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. For outputs of 1, this dc motor controller is suitable. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 9V~36V. Suitable for a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 300kHz. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 18 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 12V. UC3874 can be searched for other relevant dc to dc converter ics. 18 pins are on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. A maximum voltage of 36V is accepted by the dc to dc regulator as an input voltage. DC regulator has a maximum frequency of 300kHz. Switching converter outputs current to the greatest value of 1A.
