LP3944ISQ Overview
The 24-WFQFN Exposed Pad package conserves board space. LED drivers designed using this technology use 8 outputs.It is possible to mount the led driver using Surface Mount.With high reliability and efficiency, this emerges as a Power Switch.It is possible for the led driver ic to operate normally at -40°C~85°C TA.There are considerable benefits for Camera Flash.A termination of 24 is used to operate the LED driver.The base of this board is configured as 24 pins.Failures may occur if the voltage supply is below 2.3V.Based on our estimates, there are 8 segments.There is a mounting of it by Surface Mount.The LED driver is available under the part number LP3944.It is acceptable for the supply voltage to be 5.5V.In addition, its characteristics are classified into Display Drivers.For maximum efficiency, it requires a minimal supply voltage of 2.3V.When the supply current should be less than 550μA, the device will provide high efficiency.
LP3944ISQ Features
Available in the 24-WFQFN Exposed Pad package
Operating temperature of -40°C~85°C TA
Supply voltage of 5V
