LM3557SDX-2 Overview


In order to save board space, the 8-WFDFN Exposed Pad package is used. A LED driver using this design has 1 outputs.As a mounting method, Surface Mount is used.It emerges as a DC DC Regulator with high efficiency.It is possible for the led driver ic to operate normally at -40°C~85°C TA.The benefits of Backlight are considerable.The system operates at a frequency of 1.2MHz.For its operation, terminations with a value of 0 are used.A configuration of this chip is made up of 8 pins.It is inevitable that there will be undetermined failures when the supply voltage is less than 2.7V.A total of 5 segments have been created.It's mounted in Surface Mount.Part number LM3557 represents this LED driver.In addition, it has 8 pins.It is necessary to use 7.5V voltage to power systems.As long as the switching frequency is maintained at 1.25MHz, this electronic component is able to perform all of its functions properly.A 26V voltage is output by it.A circuit operated by the device has 3.6V volts.Input voltages higher than or equal to 2.7V make its operation much more convenient.
