UC3849DW Overview
There is a package of Tube for it. It is offered in the 24-SOIC (0.295, 7.50mm Width) package in order to save space. It is obstructing Surface Mount. The temperature should always be kept at 0°C~70°C TA when the system is operating. In Secondary-Side Controller, it is a good choice for its exceptional performance. In this case, high efficiency can be achieved because the supply voltage is 8V~20V. In this device, the analog IC SWITCHING CONTROLLER is used. In total, it has 24 terminations. There is a peak in the reflow temperature of 260. In total, it consists of 24 pins. 21mA current is supplied. Accordingly, a nominal input voltage of 12V is designed to meet the operational requirements. As a minimum, the device's input voltage should be 8V. At maximum, the device can operate at 550kHz switching frequency.
