LT3475EFE-1#PBF Overview
There is also a 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package that is used to save space on the board. LED drivers with this design have 2 outputs.To mount, use Surface Mount.As a result, it appears as a DC DC Regulator with a high efficiency and a high degree of reliability.It is capable of operating at a temperature of -40°C~85°C TA. Automotive, Backlight, Lighting has considerable advantages.As a result, it operates based on the frequency of 200kHz~2MHz.The terminations 20 are designed for its operation.With 20 pins at the base, this LED driver has a base configuration.It is possible that failures will occur if the voltage supply is below 3.7V.1 segments exist.The LED driver is based on part number LT3475.A maximum supply voltage of 36V is acceptable.In addition, it has 20 pins.At a voltage of 4V, it operates at a minimal input voltage.As a result, it runs at a minimal voltage of 4V in order to achieve the best efficiency.36V is the maximum value of the supply current.Loads can only be powered by 1.5A current.As long as the switching frequency is maintained at 600kHz, this electronic component is able to perform all of its functions properly.
