LM3502SQX-44/NOPB Overview
Using its 16-WFQFN Exposed Pad package, it is possible to save board space. Using this LED driver, there are 2 outputs.Surface Mount is used to mount the led driver.With high reliability and efficiency, this emerges as a DC DC Regulator.It is capable of operating at a temperature of -40°C~85°C TA. Backlight has significant advantages.It operates at 1MHz frequency.There are 16 pins used to form the base of its configuration.A voltage supply below 2.5V may cause undetermined failures.Segments counted are 10.LED drivers have a base part number of LM3502.44V is the voltage output.The voltage range of this device is optimized for a maximum supply voltage of 5.5V.Operating temperatures should not exceed 85°C in order to ensure stable operation.Stable operation requires an operating temperature greater than -40°C.In order for systems to function, a voltage of 0 is required internally.This electronic component may perform its functions fully if the switching frequency is maintained at 1MHz.A current of 1.9mA is consumed in the absence of external influences.
