LM27951SDX/NOPB Product Details

LM27951SDX/NOPB Overview


On the board, there is also a 14-WFDFN Exposed Pad package that saves space.Surface Mount is used to mount the led driver.DC DC Regulator emerges with high efficiency and reliability.It is possible for the led driver ic to operate normally at -40°C~85°C TA.There are many benefits for Backlight.In this case, it uses 14 terminations.This configuration is built upon 14 pins.If the voltage supply is less than 2.8V, undetermined failures will occur.A total of 4 segments are estimated.It is mounted in the way of Surface Mount.It's under the LM27951 base part number.It is acceptable to supply voltages of 5.5V volts.The output voltage is 2.5V~3.9V.Further, it can be classified as Display Drivers based on its characteristics.For maximum efficiency, it requires a minimal supply voltage of 2.8V.It's possible for this electronic component to fully function when the switching frequency is maintained at 750kHz.A current of 1.5mA is consumed in the absence of external influences.
