UC3844AN Overview


The switching controller fits in the 8-DIP (0.300, 7.62mm) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 10V~30V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TA. Using this switching controller, it is possible to switch at Up to 500kHz. The Through Hole allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. UC3844 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 8 pins. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 5V voltage based on test statistics. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. A frequency of 450kHz is set for the switching controller. A dc switching in a dormant state uses 11mA. It is possible to set the input voltage to 15V for nominal working status. The supply voltage should be 11V. It is not recommended to supply more current to the controller than 25mA. If there is 11mA current flow input, then the switching converter could operate.
