LM3557SDX-2/NOPB Overview
In order to save board space, the led driver uses the 8-WFDFN Exposed Pad package. LED drivers use 1 outputs for their design.This mounting method is Surface Mount.As a DC DC Regulator, it has high efficiency and reliability.It is possible for the led light driver to operate at a temperature of -40°C~85°C TA.The benefits it provides to Backlight are considerable.As a result, it operates based on the frequency of 1.2MHz.In this case, the termination value is 8.This configuration is built upon 8 pins.It is inevitable that there will be undetermined failures when the supply voltage is less than 2.7V.The segment count is 5.The LED driver is based on part number LM3557.In order for systems to function, a voltage of 0 is required internally.Electronic components can function properly when their switching frequency is set to 1.25MHz.When operating the device, 3.6V volts are assigned to the circuit.When the input voltage is greater than or equal to 2.7V, the operation of this device is greatly simplified.
