LM3551SD Overview

There is also a 14-WFDFN Exposed Pad package that is used to save space on the board. Using this LED driver, there are 1 outputs.As far as mounting is concerned, Surface Mount is adopted.DC DC Regulator emerges with high efficiency and reliability.If the led driver ic is set to -40°C~85°C TA, it will work normally.Camera Flash has many advantages.It operates with terminations of 14.This LED driver is configured with a base of 14 pins.It is estimated that there are 2 segments.It's mounted by Surface Mount.Under the base part number LM3551, you will find this LED driver.Ideally, the supply voltage should be 5.5V.In addition, it is equipped with a total of 14 pins.Additionally, it is categorized into Display Drivers according to its characteristics.It operates at a voltage of 2.7V as its minimal input voltage.To meet highest efficiency standards, it works on a supply voltage of 2.7V.Supply current cannot exceed 5.5V.There is no current available to supply to the load.The electronic component can fully perform its functions if the switching frequency is maintained at 1.25MHz.LED drivers can deliver all benefits of 1A due to their maximum output current.A current of 1.47mA is consumed in the absence of external influences.This device has a voltage output of 12.4V volts.5.5V should be the maximum output voltage.
