UC3849QTR Overview

The package is in the format Tape & Reel (TR). The 28-LCC (J-Lead) package is available to save space. Surface Mount instructs that it should be mounted in the following manner. The temperature should always be kept at 0°C~70°C TA when the system is operating. Its exceptional performance makes it an excellent choice for Secondary-Side Controller. High efficiency can be achieved thanks to the 8V~20V supply voltage. It has a base part number of UC3849, which can be used to locate similar components. A total of 21mA current has been supplied to the device. With the 28 pins, it is designed in a very simple way. A supply current of 21mA powers the device. Based on the Surface Mount method, it is mounted. Voltage remains constant at 8.4V. In this device, there are 1 outputs. Operating temperatures must be lower than 85°C. In order to operate, the temperature should be greater than 0°C. It is important to note that 250mA indicates the output current.
