LM27951SDX Overview
Using its 14-WFDFN Exposed Pad package, it is possible to save board space. LED drivers with this design have 4 outputs.As far as mounting is concerned, Surface Mount is adopted.As a result, it appears as a DC DC Regulator with a high efficiency and a high degree of reliability.LED drivers capable of operating at -40°C~85°C TA can be used.Backlight has considerable advantages.A termination of 14 is used to operate the LED driver.There are 14 pins on its base.A voltage supply less than 2.8V will cause undetermined failures.The number of segments is estimated to be 4.The device has been mounted on the Surface Mount.LED drivers can be found under the base part number LM27951.5.5V is an acceptable maximum value for the supply voltage.This device produces a voltage of 2.5V~3.9V volts.There are 14 pins on it.In addition to Display Drivers, [1] is assigned in accordance with its characteristics.For maximum efficiency, it requires a minimal supply voltage of 2.8V.The electronic component can fully perform its functions if the switching frequency is maintained at 750kHz.A current of 1.5mA is consumed in the absence of external influences.
LM27951SDX Features
Available in the 14-WFDFN Exposed Pad package
