LM27951SD Overview
In order to save board space, the led driver uses the 14-WFDFN Exposed Pad package. Surface Mount is used for mounting the led light driver.As a DC DC Regulator, it has high efficiency and reliability.It is possible for the led driver ic to operate normally at -40°C~85°C TA.The benefits of Backlight are considerable.The system operates with a termination of 0.This LED driver is configured with a base of 14 pins.If the voltage supply is below 2.8V, undetermined failures may occur.The number of segments is estimated to be 4.The device has been mounted on the Surface Mount.It's under the LM27951 base part number.In this device, the output voltage is 2.5V~3.9V volts.There are 14 pins on this device.In addition, it can also be categorized into Display Drivers based on its characteristics.When the input voltage is set to 2.8V, it operates.Supply current cannot exceed 5.5V.You can supply 30mA current to the load.Powering systems requires 5.5V voltages.When the switching frequency is maintained at 750kHz, this electronic component is able to fully play its functions.A current of 1.5mA is consumed in the absence of external influences.
