UC2844AD Product Details

UC2844AD Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10V~30V. Qualified to work in a -40°C~85°C TA dc switcher. This switching controller 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. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a DUAL terminal on the switching converters. A variety of 14 terminations are available in dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "UC2844" will return other relevant dc to dc converter ics. 14 pins are present on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 15V. 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 maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. The switching controller works at a frequency of 450kHz. It is possible to set the input voltage as 25V for nominal working statuses. A supply voltage of 11V is required. Current supplied to the controller should not exceed 25mA. 11mA current flow input could satisfy the switching converter for operation.
