On the board, there is also a 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package that saves space.For the design of this LED driver, 1 outputs are used.We are using Surface Mount as the mounting method.It emergys as a DC DC Controller  with high efficiency and reliable performance.It is capable of operating at a temperature of -40°C~150°C TJ. A number of benefits are available to Automotive.It operates at 700kHz frequency.For its operation, terminations with a value of 0 are used.It is possible for undetermined failures to occur if the voltage supply is lower than 4.2V.A total of 4 segments are estimated.The mount is on its way to Surface Mount.An acceptable maximum value for the supply voltage is 50V.This LED driver belonging to the Automotive, AEC-Q100 series is a key component for a broad range of applications.
