LM3503SQ-35 Overview


To save space on the board, it has a 16-WFQFN Exposed Pad package. Typically, LED drivers have 2 outputs.For mounting, it uses the Surface Mount method.It emergys as a DC DC Regulator with high efficiency and reliable performance.When the temperature is -40°C~85°C TA, it can work normally.There are considerable benefits for Backlight.It operates with 16 terminations.To form its configuration, there are 16 pins.A total of 10 segments have been created.The device has been mounted on the Surface Mount.Under the base part number LM3503, you'll find this LED driver.It is acceptable to operate with a supply voltage of 5.5V.The voltage at the output terminal is 35V.16 pins are used on the device.Furthermore, it can be categorized as Display Drivers based on its characteristics.It operates with the minimal input voltage of 2.5V.The maximum efficiency standards can be met by operating at the minimal voltage of 2.5V during operation.There is 5.5V maximum value for supply current.Loads can only be powered by 20mA current.As long as the switching frequency is maintained at 1MHz, this electronic component is able to perform all of its functions properly.A current of 1.9mA is consumed in the absence of external influences.If the output voltage exceeds 35V, it should be corrected.
