LP3944ISQX Overview

There is a 24-WFQFN Exposed Pad package on the board that is used to save space. LED drivers designed using this technology use 8 outputs.Surface Mount represents this mounting method.With high efficiency, it emerges as a Power Switch.The LED driver is capable of operating at a temperature of -40°C~85°C TA.There are significant benefits for Camera Flash.For its operation, terminations with a value of 0 are used.The configuration of the board is built around 24 pins.Under 2.3V voltage supply, undetermined failures may occur.There are estimated to be 8 segments.It's under the LP3944 base part number.Moreover, it can be classified as Display Drivers due to its characteristics.If the maximum current supply is less than 550μA, this device provides high efficiency.Systems require 5.5V voltage to operate.
