LP8543SQ Overview
To save space on the board, it has a 24-WFQFN Exposed Pad package. Using this LED driver, there are 7 outputs.Surface Mount is used for mounting the led light driver.It emerges as a DC DC Regulator, which is efficient and reliable.This LED driver can be operated at a temperature of -40°C~85°C TA. There are considerable benefits for Backlight.Based on the frequency of 625kHz~1.25MHz, it operates.In this case, the termination value is 24.With a base of 24, this LED light driver is configured.A voltage supply less than 5.5V could result in undetermined failures.We estimate that there are 12 segments.The device has been mounted on the Surface Mount.It is under the base part number LP8543 that the LED driver can be found.The output voltage of this device is 40V.This model is designed to offer 22V as its maximum supply voltage.According to its characteristics, it is also categorized into Display Drivers.
