LT3478EFE-1 Overview


It saves board space with the 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package. LED drivers with this design have 1 outputs.It is possible to mount the led driver using Surface Mount.With high reliability and efficiency, this emerges as a DC DC Regulator.The led light driver operates normally at -40°C~125°C TJ. The benefits are considerable for Backlight.Based on the frequency of 200kHz~2.25MHz, it operates on the basis of a pulse.It operates with terminations of 16.Undetermined failures will occur if the voltage supply is less than 2.8V.There are 6 segments.The device has a voltage output of 42V volts.A total of 16 pins are present on this device.A maximum voltage of 36V is optimized for use by this device.As a result, it can also be classified as Display Drivers.LED drivers belonging to the True Color PWM? series are used in a wide variety of applications.
