LT8391EFE Overview


There is a 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package on the board that is used to save space. A LED driver using this design has 1 outputs.We are using Surface Mount as the mounting method.In this case, it emerges as a DC DC Controller with a high efficiency.If the led driver ic is set to -40°C~125°C TJ, it will work normally.There are significant benefits for Automotive, Lighting.In this case, the frequency is 150kHz~650kHz.A termination of 28 is used to operate the LED driver.The voltage supply can fail if it is below 4V.LED drivers have a base part number of LT8391.Its output voltage is 0V~60V.There are 28 pins on this device.It is designed to provide an output voltage of 60V as its maximum value.Working with an input voltage higher than or equal to 4V brings great convenience to its operation.High stability can be ensured when the input voltage is kept below 60V.

LT8391EFE Features


Available in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package
