UC3849DW Product Details

UC3849DW Overview


The package is in the format Tube. To save space, it is offered in the 24-SOIC (0.295, 7.50mm Width) package. It is mounted in the same way as Surface Mount. A temperature of 0°C~70°C TA should be maintained when the device is functioning. With its exceptional performance, it is an excellent choice for Secondary-Side Controller. As a result of the 8V~20V supply voltage, high efficiency is possible. This device has an analog IC SWITCHING CONTROLLER. There are 24 terminations in total. There is a peak in the reflow temperature of 260. It is equipped with a total of 24 pins. Using UC3849 as its base part number, similar components can be found. In Switching Regulator or Controllers, this device is included. Using 24 pins, it is designed. For powering this DC DC switching regulator, a supply current of 21mA is used. As a result of its specification, it has a nominal input voltage of 12V. A constant output voltage is maintained at 8.4V. This device is equipped with 1 outputs. A value of 250mA is set for the output current.
