LT3954IUHE#PBF Overview


The QFN package is used for saving board space. In LED drivers, the outputs are all set to 1.In the 1MHz frequency range, it operates.The base of this board is configured as 28 pins.Based on our estimates, there are 8 segments.In this case, 40V is acceptable.There is a voltage output of 40V.At a voltage of 4.5V, it operates at a minimal input voltage.For highest efficiency, it works with a minimal supply voltage of 4.5V.When the maximum supply current is allowed, the value reaches 40V.In order to ensure stable operation, the operating temperature should not exceed 125°C.Maintaining a temperature above -40°C is essential for stabilizing operation.Make sure the output current is set to 0 for the part.
