    Products Detail

    SG3543DW Overview


    The package is in the format Bulk. The 16-SOIC (0.295, 7.50mm Width) 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 when the system is operating. Its exceptional performance makes it an excellent choice for Power Supply, Supervisor. High efficiency can be achieved thanks to the 4.5V~40V supply voltage. As part of this device, an analog IC POWER SUPPLY SUPPORT CIRCUIT is used. In total, there has been 16 terminations of this process. There is a peak in the reflow temperature of 260. It has a base part number of SG*543, which can be used to locate similar components. Having the supply voltage at 10V makes it possible to achieve high efficiency. Access to 1 channels is possible. In Power Management Circuits, this device is included. It is standard for the supply voltage (Vsup) to be higher than 4.7V for normal operation. With the 16 pins, it is designed in a very simple way. 40V is the maximum supply voltage. A supply current of 7mA powers the device. Based on the Surface Mount method, it is mounted. This device relies on 4.5/40V power supplies for its energy.
