LP3944ISQX/NOPB Product Details
LP3944ISQX/NOPB Overview
Board space is saved by its 24-WFQFN Exposed Pad package.To mount, use Surface Mount.The system emerges as a Power Switch with high efficiency.It is possible for the led light driver to operate at a temperature of -40°C~85°C TA.Camera Flash has significant advantages.It operates with 24 terminations.A configuration of this chip is made up of 24 pins.It is possible for undetermined failures to occur if the voltage supply falls below 2.3V.There are 8 segments in it.There is a device mounted on the Surface Mount.Under the base part number LP3944, you will find this LED driver.It is acceptable to supply voltages of 5.5V.In addition, its characteristics are classified into Display Drivers.The maximum efficiency can be achieved by operating it at a minimal voltage of 2.3V.As long as the maximum supply current is under 550μA, it can deliver high efficiency.350μA current is consumed in the case of no external factors.
LP3944ISQX/NOPB Features
Available in the 24-WFQFN Exposed Pad package Operating temperature of -40°C~85°C TA Supply voltage of 5V
