UC3849Q Overview
There is a Tube package attached to it. To save space, it is offered in the 28-LCC (J-Lead) package. It is mounted according to Surface Mount. As long as 0°C~70°C TA is maintained, the device should function properly. For Secondary-Side Controller, it is an excellent choice due to its exceptional performance. Because of the 8V~20V supply voltage, high efficiency is possible. This device contains an analog integrated circuit SWITCHING CONTROLLER. There are 28 terminations in total. There is a peak temperature of NOT SPECIFIED during reflow. In order to find comparable components, the part number is UC3849. This is a part of Switching Regulator or Controllers that has been included. The design uses 28 pins. A supply current of 21mA powers the device. The method of Surface Mount is used to mount it. Accordingly, a nominal input voltage of 12V is designed to meet the operational requirements. A constant output voltage is maintained at 8.4V. This device comes with 1 outputs. 250mA is set as the output current.
