LM3503SQX-44 Product Details

LM3503SQX-44 Overview


To save space on the board, it has a 16-WFQFN Exposed Pad package. Typically, LED drivers have 2 outputs.For mounting, it uses the Surface Mount method.With high efficiency, it emerges as a DC DC Regulator.When the temperature is -40°C~85°C TA, it can work normally.Backlight provides many benefits.In order for it to operate, it has 16 terminations.This configuration is built upon 16 pins.It is inevitable that there will be undetermined failures when the supply voltage is less than 2.5V.It is estimated that there are 10 segments.This is mounted by Surface Mount.Under the base part number LM3503, you will find this LED driver.5.5V is a maximum acceptable voltage for the supply.This device produces a voltage of 44V volts.In this device, there are 16 pins.As a result, its characteristics can also be categorized as Display Drivers.This electronic component can fully perform when the switching frequency is 1MHz.In the absence of external factors, 1.9mA current is consumed.
