LTC2945CUD-1#PBF Overview
Package Tube contains it. In order to save space, it comes in the 12-WFQFN Exposed Pad package. It is mounted in the same way as Surface Mount. As long as 0°C~70°C is maintained, the device should function properly. In General Purpose, it is a good choice for its exceptional performance. The 2.7V~5.9V supply voltage allows for high efficiency. An analog IC is used in this device, which is set to POWER SUPPLY SUPPORT CIRCUIT in this case. As a result of its termination, it has a total of 12. Reflow temperature peaks at NOT SPECIFIED. In total, it has 12 pins. Similar components can be discovered with its base part number of LTC2945. Having the supply voltage at 5V makes it possible to achieve high efficiency. The number of channels available is 1. Power Management Circuits includes this device. Keeping the supply voltage (Vsup) above 2.7V is necessary for normal operation. The device is designed with 12 pins. 80V is the maximum supply voltage. The DC DC switching regulator is powered by a supply current of 800μA. The system is powered by 4/80V power supplies. Input voltage 4V~80V is provided. A maximum current of 1.2mA is available from the supply.
