LM3549SQ/NOPB Overview
In order to save board space, the 24-WFQFN Exposed Pad package is used. It is mounted using Surface Mount.With high reliability and efficiency, this emerges as a DC DC Regulator.The led light driver is capable of working normally at -30°C~85°C TA.A frequency of 2.4MHz is used to operate it.The operation of this system is supported by 24 terminations.This LED driver is configured with a base of 24 pins.If the voltage supply is lower than 2.7V, undetermined failures may occur.There are 3 segments in it.It's mounted in Surface Mount.LED drivers can be found under the base part number LM3549.It's acceptable for the voltage to be 5.5V.The device has a voltage output of 4.6V volts.Moreover, it can be classified as Display Drivers due to its characteristics.For maximum efficiency, it operates at the minimal voltage of 2.7V.There is no external factor that consumes current when there is 1.6mA current consumption.
