LM3509SD/NOPB Overview
To save space on the board, it has a 10-WFDFN Exposed Pad package. LED drivers use 2 outputs for their design.Mounting is done according to the Surface Mount method.Initially, it emerges as a DC DC Regulator with high efficiency and a high degree of reliability.It is possible for the led driver ic to operate normally at -40°C~85°C TA.Backlight has many advantages.It operates at 1.27MHz frequency.In this case, the termination value is 10.A configuration of this chip is made up of 10 pins.A voltage supply less than 2.7V will cause undetermined failures.In total, it includes 10 segments.This is mounted by Surface Mount.It is under the base part number LM3509 that you can find this LED driver.It is acceptable to have a maximum voltage of 5.5V.The voltage output by it is 21V.Additionally, it is categorized into Display Drivers according to its characteristics.For maximum efficiency, it operates at the minimal voltage of 2.7V.When the maximum supply current is below 440μA, the device can deliver high efficiency.In this case, the load can only be supplied with 30mA current.When the switching frequency is maintained at 1.25MHz, this electronic component is able to fully play its functions.900μA current is consumed in the case of no external factors.
