LM3509SDX/NOPB Overview
Using its 10-WFDFN Exposed Pad package, it is possible to save board space. These LED drivers have 2 outputs.As far as mounting is concerned, Surface Mount is adopted.With high efficiency, it appears as a DC DC Regulator.The led light driver operates normally at -40°C~85°C TA. It is clear that Backlight will benefit from the program.The system operates at a frequency of 1.27MHz.10 terminations are used in its operation.There are 10 pins used to form the base of its configuration.If the voltage supply is lower than 2.7V, undetermined failures may occur.The segment count is 10.Surface Mount is mounted on it.LM3509 is the base part number for the LED driver.5.5V is an acceptable maximum value for the supply voltage.The output voltage is 21V.In addition, it can be classified as Display Drivers according to its characteristics.In order to achieve the highest efficiency, it is designed to operate at a low voltage of 2.7V.Electronic components can function properly when their switching frequency is set to 1.25MHz.The consumption of current is 900μAin the absence of external factors.
