LM3503SQ-16/NOPB Overview
There is a 16-WFQFN Exposed Pad package on the board that is used to save space. In LED drivers, the outputs are all set to 2.Mounting is done according to the Surface Mount method.DC DC Regulator emerges with high efficiency and reliability.The led light driver operates normally at -40°C~85°C TA. Backlight has significant advantages.It is designed to work with 16 terminations.The base of this board is configured as 16 pins.Under 2.5V voltage supply, undetermined failures may occur.Based on our estimates, there are 10 segments.Surface Mount is mounted in the way.LED drivers are found under the base part number LM3503.It is acceptable for the supply voltage to be 5.5V.The output voltage of this device is 16V.In addition, its characteristics are classified into Display Drivers.For highest efficiency, it works with a minimal supply voltage of 2.5V.When the maximum supply current is below 3mA, it is capable of delivering high efficiency.Loads can only be powered by 650mA current.As long as the switching frequency is maintained at 1MHz, this electronic component is able to perform all of its functions properly.There is no external factor that can consume current, so 1.9mA current is consumed.
