UC3844D8TRG4 Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 12V~28V volts and has 12V~28V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. There is a switch at Up to 500kHz that can be used with this controller. dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 8 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. In addition to "UC3844", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 8 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. A 13.5V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. The switching controller works at a frequency of 450kHz. 25V is the nominal working voltage. 25mA more than 25mA current should be supplied to the controller.
