LP3943ISQX/NOPB Overview
The 24-WFQFN Exposed Pad package is used for saving board space. We are using Surface Mount as the mounting method.It is highly reliable and high-performing when it emerges as a Power Switch.The led light driver operates normally at -40°C~85°C TA. A number of benefits are available to Camera Flash.In this case, the termination value is 24.To form its configuration, there are 24 pins.If the voltage supply is below 2.3V, undetermined failures may occur.The number of segments is 16.Surface Mount has been mounted with the device.A base part number of LP3943 is associated with this LED driver.It is acceptable for the supply voltage to be 5.5V.As a result, it can also be classified as Display Drivers.With a minimal supply voltage of 2.3V, it reaches the highest efficiency levels.When the maximum supply current is below 550μA, the device can deliver high efficiency.There is no external factor that can consume current, so 350μA current is consumed.
