LT3956EUHE#PBF Overview


There is also a 36-WFQFN, 28 Leads, Exposed Pad package that is used to save space on the board. These LED drivers have 1 outputs.It is mounted using Surface Mount.There is no doubt that this is a very efficient and reliable DC DC Regulator.It is capable of operating at a temperature of -40°C~125°C TJ. A frequency of 100kHz~1MHz is used to operate it.In this case, the terminations are set to 28.The voltage supply can fail if it is below 4.5V.There is a base part number LT3956 for this LED driver.This device contains 36 pins.An optimized supply voltage of 80V is provided.Operation of the device requires 24V volts to be applied to the circuit.It is greatly simplified when used with input voltages greater than or equal to 4.5V.Moreover, this LED driver is characterized by ALSO OPERATES AS LDO REGULATOR.Input voltages below 80V can assure high stability.There should be no more than 4.6A current coming out of the output.
