UCC3581DTR Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 6.8V~15V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. With this switching controller, you can switch at Up to 100kHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. 14 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 10V. In addition to "UCC3581", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 7.4V. As determined by the test statistics, the output voltage of DC regulator is 600mV. It's important to remember that the dc dc regulator's normaloutput current is 100mA, so you should note it down when starting a new project. It is set to 84 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. A frequency of 100kHz is set for the switching controller.
