UC2844AD8TR Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tape & Reel (TR). 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. Qualified to work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position DUAL . Different dc switching's functions can be applied to 8 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. In addition to "UC2844", there are other relevant dc to dc converter ics you can find. The switching converter has a total of 8 pins. There is a particular type of Switching Regulator or Controllers in switching converter. DC regulator outputs 15V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. The maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. 450kHz is the frequency of the switching controller. For nominal working status, the input voltage can be set as 25V. The supply voltage should be 11V. 25mA more than 25mA current should be supplied to the controller.
