UCC2581D Overview


In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tube. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 6.8V~15V. Suitable for a -40°C~85°C TA dc switcher. Switching can be done at Up to 100kHz with this switching controller. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Soft Start which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. The 14 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 10V. Search for "UCC2581" to find other relevant dc to dc converter ics. Total pins of switching converter are 14. Switching converter is a type of Switching Regulator or Controllers in particular. 7.4V should be the minimum input voltage for the dc dc voltage regulator. A 600mV voltage of DC regulator was detected in the test statistics. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 87 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 100kHz is used by the switching controller. Switching controller is necessary to supply a voltage of 4V. A supply current of 300μA is used to power it. Switching voltage regulators' nominal current supply is 300μA.
