LM3503SQ-25/NOPB Overview


The 16-WFQFN Exposed Pad package saves space on the board. LED drivers designed using this technology use 2 outputs.Surface Mount is used to mount the led driver.It emergys as a DC DC Regulator with high efficiency and reliable performance.It is possible for the led driver ic to function normally at -40°C~85°C TA.There are considerable benefits for Backlight.It operates with 16 terminations.This configuration is built upon 16 pins.A voltage supply less than 2.5V will cause undetermined failures.There are estimated to be 10 segments.It's mounted in Surface Mount.LM3503 is the base part number for this LED driver.It is acceptable to operate with a supply voltage of 5.5V.The voltage at the output terminal is 25V.Further, its characteristics allow it to be classified as Display Drivers.For maximum efficiency, it requires a minimal supply voltage of 2.5V.When the supply current should be less than 3mA, the device will provide high efficiency.It is possible to supply the load with 800mA current.Electronic components can function properly when their switching frequency is set to 1MHz.No external factors cause 1.9mA current to be consumed.
