LM3549SQX/NOPB Overview


In order to save board space, the led driver uses the 24-WFQFN Exposed Pad package. Surface Mount is used for mounting.It emerges as a DC DC Regulator with high efficiency.The led light driver operates normally at -30°C~85°C TA. It operates at 2.4MHz frequency.In this case, it operates with terminations of 0.The LED light driver is configured with a base of 0 pins.It is inevitable that there will be undetermined failures when the supply voltage is less than 2.7V.A total of 3 segments have been created.It's mounted on the way to Surface Mount.This LED driver has the part number LM3549.It is acceptable to operate with a supply voltage of 5.5V.There is 4.6V voltage output from this device.Further, its characteristics allow it to be classified as Display Drivers.As a result, it is designed to operate at a minimal voltage of 2.7V to ensure the most efficiency possible.The consumption of current is 1.6mAin the absence of external factors.
