UC2845D8 Product Details

UC2845D8 Overview


In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 12V~28V volts and has 12V~28V supply voltage. Work well in dc switchers with a -40°C~85°C TA. With this switching controller, you can switch at 500kHz. A generalization of dc dc regulator can be made using Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. DUAL are the position of the terminal of the switching converters. The 8 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "UC2845", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 13.5V. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. Switching controllers operate at 450kHz frequencies. A nominal working status is achieved when the input voltage is set to 25V. It is not recommended to supply more current to the controller than 25mA. It runs on a supply current of 17mA. This the controllers dc receives a 17mA nominal current supply.
