LM3551SD/NOPB Overview
There is also a 14-WFDFN Exposed Pad package that is used to save space on the board. This LED driver has 1 outputs.The mounting method is Surface Mount.The system emerges as a DC DC Regulator with high efficiency.It is capable of operating at a temperature of -40°C~85°C TA. There are considerable benefits for Camera Flash.There are 14 terminations that are designed to operate with it.The base is configured with 14 pins.This is mounted by Surface Mount.LED drivers can be found under the base part number LM3551.As a result, it can also be classified as Display Drivers.As its minimal input voltage, it operates at 2.7V.When the maximum supply current is allowed, it reaches 5.5V.If the maximum current supply is less than 2mA, this device provides high efficiency.Loads can only be powered by 1A current.This electronic component may perform its functions fully if the switching frequency is maintained at 1.25MHz.When operating with a maximum output current of 1A, it can deliver all the benefits of a LED driver.A current of 1.47mA is consumed in the absence of external influences.Currently, it is generating 20V voltage.
