UC3874DWTR-1 Overview


Capsuled in the 18-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control operates at 9V~36V and has a 9V~36V supply voltage. Qualified to work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 300kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. An array of 18 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. This dc to dc regulator accepts only 36V input voltage at most. Whenever the current value is 1A, switching converter outputs the highest possible value.
