UC3844NG4 Overview

With a 8-DIP (0.260, 6.60mm) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. 12V~28V is the operating voltage and supply voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. Switching can be done at Up to 500kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Through Hole. DCDC regulator is controlled efficiently by Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Various 8 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. A search for "UC3844" will reveal other relevant dc to dc converter ics. There are only 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. A 5V voltage of DC regulator was detected in the test statistics. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 50 %. A frequency of 450kHz is used by the switching controller. For nominal working status, the input voltage can be set as 25V. In order to ensure proper operation, the controller should not receive more current than 25mA. 11mA current flow input could be used to operate the switching converter .
