UC2844D8TR Overview


This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. The dc motor controller is adquate to generate for 1 outputs. An enclosure of Tape & Reel (TR) is used to package the PMIC. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 12V~28V voltage are supplied and operated. Work well in dc switchers with a -40°C~85°C TA. The switching controller is capable of switching at the Up to 500kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. Various 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. In addition to "UC2844", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Based on the test statistics, DC regulator outputs voltage 13.5V. If you start a project, note down the dc dc regulator's usual output current of 200mA. 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 set for the switching controller. For nominal working status, the input voltage can be set as 25V. There should be 25mA current exceeding 25mA supplied to the controller.
