UC2845DTR Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. dc controls with 12V~28V voltage are supplied and operated. Suitable for work in a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 500kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 14. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 15V. In addition to "UC2845", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. As determined by the test statistics, the output voltage of DC regulator is 13.5V. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. This Surface Mount makes DC switcher suitable for most prototypes and applications. There is 450kHz frequency setting on the switching controller. 25V is the nominal working voltage. There should be 25mA current exceeding 25mA supplied to the controller.
