UC2844D8 Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. An enclosure of Tube is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 12V~28V voltage are supplied and operated. A -40°C~85°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics will be returned if you search "UC2844". The switching converter has a total of 8 pins. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 13.5V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. 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. Current supplied to the controller should not exceed 25mA.
