LM3557SD-2/NOPB Overview
Using its 8-WFDFN Exposed Pad package, it is possible to save board space. This LED driver has 1 outputs.The led driver mounting is done by using Surface Mount.The system emerges as a DC DC Regulator with high efficiency.At -40°C~85°C TA, the led driver is capable of operating.There are considerable benefits for Backlight.This system operates at 1.2MHz frequency.In this case, the termination value is 8.Its configuration is based on 8 pins.It is possible for undetermined failures to occur if the voltage supply falls below 2.7V.Based on our estimates, there are 5 segments.I have mounted it by Surface Mount.There is a base part number LM3557 for this LED driver.In this case, 7.5V is acceptable.As a result, it runs at a minimal voltage of 2.7V in order to achieve the best efficiency.When the maximum supply current is less than 800μA, the device is able to provide a high level of efficiency.In this case, the load can only be supplied with 800mA current.When the switching frequency is maintained at 1.25MHz, this electronic component is able to fully play its functions.It has a voltage of 22V.Operation of the device requires 3.6V volts to be applied to the circuit.
