UC2849DW Product Details

UC2849DW Overview


There is a Tube package for it. As a space-saving measure, it is included in the 24-SOIC (0.295, 7.50mm Width) package. Surface Mount instructs that it should be mounted in the following manner. As long as -40°C~85°C TA is maintained, the device should function properly. The device is an outstanding choice for Secondary-Side Controller owing to its outstanding performance. High efficiency can be achieved thanks to the 8V~20V supply voltage. The device is powered by an analog IC SWITCHING CONTROLLER. It has a total of 24 terminations. During reflow, the temperature peaks at 260. It is equipped with a total of 24 pins. Using UC2849 as its base part number, similar components can be found. Currently there is 21mA current being supplied to the system. A device of this type belongs to Switching Regulator or Controllers. There are 24 pins used in the design of this board. It provides a nominal input voltage of 12V in accordance with functioning requirements. As long as 8.4V is set as the output voltage, it will remain constant. This device comes with 1 outputs. 250mA is set as the output current.
