UC3874DWTR-1G4 Product Details
UC3874DWTR-1G4 Overview
With its 18-SOIC (0.295, 7.50mm Width) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 9V~36V and has a 9V~36V supply voltage. Worked in a 0°C~70°C TA dc switcher before. In this switching controller, the switch can be set to Up to 300kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 18 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "UC3874" will return other relevant dc to dc converter ics. 18 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. It should be noted that the dc to dc regulator only accepts 36V voltage as input voltage. There is a maximum frequency of 300kHz on this dc regulators. 1A is the largest value switching converter outputs.
