LTC2945CUD#PBF Overview
Package Tube contains it. Space is saved by offering it in the 12-WFQFN Exposed Pad package. Surface Mount tells us how to mount it. In order for the system to function properly, the temperature must be kept at 0°C~70°C. As a result of its exceptional performance, it is an excellent choice for General Purpose. High efficiency can be achieved with a 2.7V~5.9V supply voltage. In this device, the analog IC POWER SUPPLY SUPPORT CIRCUIT is used. There are a total of 12 terminations associated with it. NOT SPECIFIED is the peak of the reflow temperature. There are 12 pins on this device. Using the LTC2945 base part number, you can find comparable components. Having the supply voltage at 5V makes it possible to achieve high efficiency. The amount of current supplied is 800μA. There are 1 channels that can be accessed. Power Management Circuits comprises this device. If the supply voltage (Vsup) is above 2.7V, normal operation can be achieved. Voltages up to 80V are set as the maximum. This device relies on 4/80V power supplies for its energy. It is provided with an input voltage of 4V~80V. A maximum supply current of 1.2mA is possible.
