LT3954IUHE Overview
To save space on the board, it has a 36-WFQFN, 28 Leads, Exposed Pad package. In LED drivers, the outputs are all set to 1.Surface Mount is used to mount the led light driver.With high efficiency, it emerges as a DC DC Regulator.It is possible for the led driver ic to operate normally at -40°C~125°C TJ.Based on the frequency of 100kHz~1MHz, it operates on the basis of a pulse.For its operation, 36 terminations are designed.Undetermined failures may occur when the voltage supply is less than 4.5V.On it, there are 36 pins.40V is the maximum value of supply voltage it offers.There are many applications for this LED driver belonging to the True Color PWM? series.While operating the device, the circuit has 24V volts.Working with an input voltage higher than or equal to 4.5V brings great convenience to its operation.The LED driver is further characterized by a SEATED HT-CALCULATED.Keeping the input voltage below 40V can ensure high stability.
