LM3551SD Overview
The board's 14-WFDFN Exposed Pad package saves space. LED drivers designed using this technology use 1 outputs.Surface Mount is used to mount the led light driver.In this case, the DC DC Regulator emerges as highly efficient and reliable.At -40°C~85°C TA, the led driver is capable of operating.There are considerable benefits for Camera Flash.The operation of this system is supported by 14 terminations.There are 14 pins on its base.Based on our estimates, there are 2 segments.As you can see, it is mounted by Surface Mount.LM3551 is the base part number for this LED driver.An acceptable maximum value for the supply voltage is 5.5V.14 pins are on the device.In addition, it can also be categorized into Display Drivers based on its characteristics.This device operates with a minimum input voltage of 2.7V volts.In order to achieve highest efficiency standards, the supply voltage must be very low, preferably at 2.7V.Whenever the maximum supply current is allowed, the value reaches 5.5V.There is no current that can be supplied to the load.The electronic component can fully perform its functions if the switching frequency is maintained at 1.25MHz.When operating with a 1A output current, the LED driver delivers all the benefits.There is no external factor that consumes current when there is 1.47mA current consumption.This device produces a voltage of 12.4V as its output.It is recommended that the output voltage be no higher than 5.5V.
