LM3557SDX-2 Product Details

LM3557SDX-2 Overview


Using its 8-WFDFN Exposed Pad package, it is possible to save board space. This LED driver has 1 outputs.The mounting method is Surface Mount.When it emerges as a DC DC Regulator, it shows high-performance and reliability.It is possible for the led driver ic to operate normally at -40°C~85°C TA.There are considerable benefits for Backlight.As a result, it operates in accordance with the frequency of 1.2MHz.In this case, the terminations are set to 8.It has a base configuration of 8 pins.A voltage supply less than 2.7V will cause undetermined failures.There are estimated to be 5 segments.The mount is in the direction of Surface Mount.There is a base part number LM3557 for this LED driver.This device contains 8 pins.It is necessary to use 7.5V voltage to power systems.As long as the switching frequency is maintained at 1.25MHz, this electronic component is able to perform all of its functions properly.This device produces a voltage of 26V as its output.The circuit is assigned 3.6V volts when the device is in operation.Working with an input voltage higher than or equal to 2.7V brings great convenience to its operation.
